Ask HN: Startup to renegotiate CC interest rates on behalf customers?
In late 2009 Citicard jacked up my interest rates to 29.99% via a change in my cardholder's agreement. This was my reward for being a loyal, responsible paying customer since 2001.

Now between this, social commerce sites like Groupon and Woot!, and the fact that my dad's job is to renegotiate millions of dollars in debt with banks on behalf of large companies, I was wondering if it would be possible to use social network effects to renegotiate interest rates with each issuer on behalf of users and organize a monthly payment strike against issuers that do not lower rates.

Basically the site would ask users to supply their name, the first 6 digits of each credit card and the amount of debt on each.

FYI, the first 6 digits are known as the IIN, which identifies the issuer.

When the collective user debt for a specific credit card issuer gets high enough, the startup would organize a campaign to threaten to go on strike by a certain deadline if the issuer refused to lower APRs.

The target APRs to be negotiated would not be defined such that it would put credit card companies out of business. Instead they would be set to forcefully keep issuers honest. Different APRs would be set according to each users credit rating. i.e. a user with a credit rating of 750 might be entitled to Prime + 5.99% while someone with 720 might be entitled to Prime + 7.99%

235 million Americans have credit cards. There is certainly a market for this idea.
There are problems with thinking like this:

1) You may never be rich enough to have any wealth to dispense. This is arrogance and ignorance.

2) You ignore the plight of those today. Money isn't the only way to be charitable. Time, energy, effort, and passion can be lent to charitable causes.

I have the same thought process as you, "oh I'll be rich one day and I'll be generous and give everything and make happiness, that'll be my contribution. But not now, I've got my own problems.". I think we all have a responsibility to do something for those less fortunate, those without opportunity, those suffering. A lot of my friends in college volunteered, and it really shamed me a bit into how little I do for anyone else.

That said, give now, whatever it is you want to give.
Agreed about battery life. If I turn off data syncing and don't use my Nexus One as a smartphone, but rather just a normal phone (eschew browsing and so forth other than a quick "where's my stop on this unfamiliar public transit?") I get more than a full day of battery life. I've never tested it past a day and a half, since that's when I invariably get wherever I was going but it doesn't drop very quickly when it has less to do.
"They think about products, not technology."

How can you be so sure about their thought process? Maybe it is the other way around, they just turn it around when it comes to presenting it to the public.
Damn, I was rooting for "iTube"
No, that means sharing libraries. You're using Java libraries now. The JVM has nothing to do with Oracle.

I'm sharing libraries with Java. I don't have to wait for somebody to write a Scala version. Big difference.

The JVM is a hog but it also holds up really high well under high memory and CPU load. Much better than most other VMs.
So apparently the new age hippies were right after all.
"Facebook continues to support principles of Net neutrality for both landline and wireless networks,"

But not the principles of selling out your users whether or not they want to be sold or not.
Let’s make some other statements about as reasonable as yours (absent further supporting explanation):

The Mughal India of the 16th–19th centuries was not the India of today. That India is long dead. The India of today is basically the British Raj, plus the branding, mix of religions and whatever else the British could salvage.

The Republican party of 1860–1970 was not the Republican party of today. That GOP is long dead. The GOP of today is basically the unholy mix of Kristol & Podhoretz foreign & economic policy with Jerry Falwell & Pat Robertson social policy, plus the branding and whatever panders to fiscal conservative constituents they could salvage from the party’s historic base of support.

The field of economics of 1780–1950 was not the economics of today. That economics is long dead. The economics of today is basically the Friedmanite Chicago school, plus the branding and whatever other assets they could salvage from economics.

Now, in all three of these cases, there’s some little bit of truth behind the wholly oversimplified (to the point of wrongness) analysis. But taking these statements at face value obscures more than it reveals, and reflects a poor understanding of how cultural assimilation works in any institution or society. (And denies evolutionary change, as well; Apple today is not exactly the same as Apple of ca. 2000)

* * *

In short: you’d better have some better analysis to back yourself up here, because as it stands I think your claim is, to the first approximation, false, even if there is a tiny bit of truth to it.
Because magic like TwitterArt #140Art happens, day in, day out.
This would also have a supply and demand benefit for the people that become teachers. At the moment, a 'C+' average in high school will get you in to most teaching courses in my state. More money means more attractive means more applicants means only the better applicants get in - this means better teachers and a better system.

(And I appreciate that smarter != better, even in this case, but if teachers rarely got 'A's in their schooling life how can we expect them to challenge and inspire those who do?)

Yeah, the H1B definitely has a bunch of issues and there is that lock-in affect which is... unfortunate. I would say the employers are always aware of H1B requirements, just some choose to abuse them. You can transfer an H1B visa, but it is a bit of a time-consuming process. H1B's are also only issued in October, which is another limitation.

How long have you been in the States? Would citizenship be an option? In any event, in your case it would be appropriate to have a consultation with an immigration lawyer who can walk you through the various visas that are available and help you figure out which one best matches your situation. There are other employment visas but I am not particularly well-versed in what they are.

threaten to go on strike by a certain deadline if the issuer refused to lower APRs

That's an empty threat...the only way to get out from under the credit card company is to pay off the debt or transfer to another card. If you can transfer to another card with a lower rate, do it. If you can pay off the debt, do it.

FYI, the credit card companies don't just raise your rate to 29.99% for no reason. They only do that when you are late or over the limit. If you are a customer in good standing, just call them up and ask for a lower rate. I've lowered my rates in the past from 15% to 7% just by asking. Nowadays I don't carry a balance, so I couldn't tell you what my interest rates are.

My sense from meeting Yahoo devs is that they are ok, in that they have the credentials, but didn't seem very passionate or excited about new tech. Can you bring up some examples where Yahoo is pioneering a new field? (search, media delivery, social etc, what ever Yahoo as a company is really excited and passionate about internally...)
Because of #140ART #TWITTERART of course.

How about Hadoop? Sure Google released the Map/Reduce paper, but it was Yahoo who wrote 90+% of the current industry standard.

What about Node.js? That's pretty en vogue right now. We are currently hiring Node.js engineers and have a number of core contributors in various parts of the company.

YUI and our other front-end work at Yahoo! is world class. People like Crockford are considered leading experts in doing quality front-end web engineering.

Our data centers are also cutting edge, I'm not an expert in this area, but I'm told we are at least on par with Google. Some of the new project are completely cooler-free, the whole building being designed to control heat and power flow.
This is the dawning of the age of aquarius!
I know you're joking, but there's a general principle at work here. Suppose you make a prediction (e.g. "There will be a great cataclysm in 2010!") that later turns out to have been correct in some way (e.g. an earthquake hits Haiti). Your prediction was only useful to the extent that it could have helped someone anticipate the Haiti earthquake. A sufficiently vague statement doesn't tell people anything, even if it turns out to have been technically correct.

Bringing it back on topic: if New Age guys talk about fractal crystal handwavium, and later scientists find some genuine science involving fractals and crystals, that doesn't mean the New Age hippies predicted it. A good prediction is a specific prediction. You could call this the anti-Nostradamus principle, but really it's just a generalization of the idea that a theory ought to be falsifiable.

Could coffee be an Australian entrepreneurial success story?
Having kids has been a great change in my life. My kids are 4 and 6 now and I'm loving being a dad. I can still work long hours, but I split the hours to spend time with them. I don't have the time I'd like to have to dig into new technologies, new tools, etc, but I feel I'm a good dad. Starting to do some science experiments with my kids which is very cool.

What has worked for me is to get an early start in the morning so I can cut off work at a decent hour. Then I often will put in hours after the kids go to bed. Doing this I can still put in fairly long hours. Important thing is to review your goals and milestones and make adjustments to the time required to hit them. If the schedule was created assuming 60-70 hours a week, you will need to rethink the deadlines.

On the family front, one thing that has worked out really we for my wife and me is that we each have one night a week free, where the other is responsible for the kids. This one afternoon/evening is a nice relief. I use it to go grab some drinks with friends, play golf, hack on a project, watch a movie, etc. We both find that we are better parents (and spouses) when we get some down time.

Actually I did eaxctly what you suggested and contacted them to lower my rates. After escalating my inquiry all the way up to CEO Vikram Pandit, I learned that they do just change the rate to 29.99% for no reason. Here is the email I received today from a Citibank representative after sending an email to Vikram Pandit inquiring what I had done to cause my rates to go up.

"Thank you for your recent email to Mr. Pandit. Since your inquiry is related to your Citi(r) Bronze(r) / AAdvantage(r) card ending in XXXX, he has asked that I respond on his behalf.

Unfortunately, my recent attempts to contact you by telephone were unsuccessful. I certainly regret any inconvenience or difficulty you may have experienced in your attempts to request a reduced Annual Percentage Rate (APR) through our Customer Service area. Our goal is to serve our customers by providing superior service and products. One of the best ways to achieve this goal is to receive feedback, both positive and negative, from our customers. As the quality of the service we provide our customers is of great importance to us, I have forwarded your comments to management for review.

Our records indicate that in October 2009, your account was included in a Change in Terms to the Card Agreement, which proposed to increase your APR from Prime + 9.99%, currently 13.24% to Prime + 26.74%, currently 29.99%. We consider a number of factors when changing terms. In order to continue to provide consumers with access to credit, we need to operate under revised terms, which include an APR change. These changes are being made due to the fact that our cost of doing business continues to be impacted by the challenging market conditions. Based on this total picture, we establish what we believe is an appropriate price for our products. While we realize you are not satisfied with the new terms, we believe the new terms are consistent with the current market conditions. As explained in the notification sent to you, cardholders were provided with the opportunity to opt-out of the Change in Terms, which would have immediately closed your account but allowed you to pay any outstanding balance under the prior terms. Our records do not reflect receipt of your opt-out notification; therefore, the new terms became effective on your January 2010 billing statement."

Facebook overlooks the fact that lock-in is nearly meaningless on the web, so you can't treat your user base as a given. eBay is ignoring this. Myspace ignored this and they're nearly irrelevant now.

Companies are growing to the multi-billion dollar mark faster than ever. That trend will only continue as technological advances continue. What will happen in the near future as SSDs get better, larger, and cheaper? What will happen as multi-core CPUs continue their progression? As always, single newer machines become capable of replacing multiple older machines. At what point in the future does the equivalent storage, processing, and transactional volume capabilities of an entire datacenter of today fit into a single server room tomorrow? A single rack? A single 1U server? A single VPS instance?

In the not too distance future the ability to host applications like facebook that serve hundreds of millions or even billions of users will be just a click away and cheap enough to fall under the "ramen profitability" umbrella. Giant, billion user apps will be the viral videos of tomorrow. Companies will grow to enormous sizes not in a matter of years or months but in a matter of days, or hours.

What happens when your billion dollar, thousand dev. corporation has serious competition in the form of a 5 person startup?
You might live on an earthquake-prone island nation like Japan. Or the easiest access to cooling water may be in someplace with an earthquake risk.

Personally, I think that probably the thing to do is work on power lines that can efficiently carry vast amounts of power long distances, and build nuke plants in places that are less crazy politically than California. Reduced earthquake likelihood would be a very nice side-benefit.

awesome post, until he calls the folks he manages "rockstars." can we please all just move past that ridiculous cliche??
Well, there’s this widely used gem: ‘;-)’

Why did people suddenly adopt a symbol for clearly marking their irony when before they have not?

My hypothesis is that prior to the mass adoption of mobile phones (SMS) and the Internet (IM, e-mail, any form of chat and discussion) it was nearly impossible (well, unpractical) to have informal conversations with someone in written form. Even letters or postcards are very much unlike e-mail, a lot more formal, for the most part carefully crafted and lacking the immediacy of our new forms of written communication. We used speech for all our informal conversations up until very recently.

Everyone knows how to mark speech as ironic. You can literally wink, change the tone of your voice or just start grinning after everyone starts looking at you with disbelief. When authors wanted to use irony in their works they had the time, space and skills to create a setup which marks something as irony, a typographic sign would probably have seemed like cheating to them (much like overuse of the exclamation mark would).

But suddenly there are all these people who are not authors and who write all the time if they want to have a conversation. Time, space and skills – the three of those are not readily available when chatting. (And why should they, why should you suddenly invest more time to conduct your informal conversation just because it is in written form?)

I think it works quite well, actually, for what it is, compared to its cousin in spoken informal conversations at least. Sure, it’s not even the same ballpark as some of the irony you can find in literary masterpieces but hardly anything we say in everyday conversations ever is.

(For testing my hypothesis I would suggest finding written pre-Internet conversations – if the is at all possible – and looking for any marks for irony or tone of voice. Pretty much seems like an impossible thing to check, if you ask me.)
It is not a kid, it is relationship bomb. Focus on the relationship.

(I heard it in some random YouTube video once, which just goes to show that good advice can be found in strange places)

Because they, as parents, are entirely responsible for the kid's very existence. Adults are, to a large degree, responsible for themselves, much as we may love them.
Yes, yes. But the original challenge is invalid. I asserted that I could implement 99% of algorithms I came across for practical real-world problems, not 99% of all algorithms.

I gave a solution that solves the problem. The problem is, convert an arbitrary concave closed polygon into a set of triangles. I maintain that it is completely valid for me to present that solution --- there are plenty of tricks you can do to optimize it in C/C++. And not just runtime optimization either... For example why not triangulate the polygon, then save the results to disk? That way O(N log N) vs O(N) becomes completely irrelevant... you only have to do it once, ever.

I suppose what I am saying is this: I can solve 99% of real-world problems I am likely to encounter in my career as a software engineer. The challenge "implement THIS scientific paper!" is completely invalid because it's a solution to a problem which very likely will never exist. My solution is valid as long as it does not greatly impact the performance of the app. Which is "always", once you throw in a layer of caching.

P.S. The paper has the restriction "for every polygon vertex XY, no two vertices may have the same Y coordinate", which means it's likely to not be applicable to any real-world problem.
