I turned to this page after the following experience (I make aggressive use of ad blockers and JS filtering generally).

This was in an incognito Chromium session where I don't run NoScript.

I was searching for some basic heat transfer references and found a page with a nice write-up on Newton's law of heat transfer. I copied the URL into the post I was composing as I was reading it. A "chat" dialog pops up asking if I need tutoring assistance. Um. No. So I ignore it.

The site then navigates me away from the page and onto a registration page.

Whiskey. Tango. Foxtrot.

My immediate and predictable response: I fired up 'sudo -e /etc/hosts' and added both hostnames to my blocklist. Though I took the courtesy of emailing the site's contact address and asking them what the actual fuck they thought they were doing.

Apparently Pearson Education have the educational market so fully sewn up they can get away with this kind of bullshit.

But seriously? What the actual fuck?

Upshot: why do people block the hell out of this stuff? It's goddamned annoying as hell.

I compiled a list some time ago on G+ that's worth repeating here:

Forbes asks: Why do programmers hate advertising so much?

First, I think it's hardly just programmers. I suspect most people find advertising to be a negative.

But as to us techies? Why do we hate thee? Let me count the ways:

1. It's intrusive. Many/most of us probably have some level of ADD/OCD. Or just plain environmental sensitivity.

2. It's distracting.

3. It promotes a host of anti-usability features: content muting, multi-page click-through articles, overly formatted pages, overlays, pop-ups, persistent floating top/right/left/bottom elements, audio, video, multiple audio/video.

4. It's creepy, and you're creeping me out. Tracking through various deceptive means, even though I've made very clear that I don't wish to be tracked. Incidentally, subscription content suffers a similar issue: I don't want an audit trail of all things I've read, even on one site, let alone across sites.

5. The ads themselves frequently position themselves to price-discriminate -- though how and when I can never be certain (which undermines the efficacy of all ads).

6. The mechanisms of advertising networks pose security issues: cross-site JS, iframes, Flash, and Java. Even just the proliferation of different JS sources creates a serious management and cognitive overload for the security- and privacy-conscious reader. A single article from a news site may contain over 20 JS sources.

7. The goods and services which are most highly advertised are those which I'm least inclined to buy. Especially for (so-called) food and entertainment, but also general consumer products, electronics, and various services, especially financial services. To the point that when I see advertising my first conscious reaction is "why do they have to try so hard to convince me that that is something worth buying?"

8. It's not relevant. There are a very limited number of times when I'm in a purchase mode. The real value of the Internet would be to (correctly) identify those times, and then find me the best deals on what I want, in the way that I want to obtain it. Which, frankly, dear, isn't online most of the damned time.

On that last point, I've been shopping in recent times for a number of moderately high-ticket items. Including spending a lot of time researching options on-line. My biggest take-away is that online purchase researching sucks massively. Contrast to the experience at a store with a well-trained, skilled retail staff. "Is this what you like?" "No, I'm looking for something that's more XXX". And as much as I disdain retail much of the time, the people who are good at it figure out what you want, what you can afford, and what they have that suits you, quickly, without wasting your time (and if you're lucky, making the exercise enjoyable).

It's something I've also addressed recently, "Search quality vs. search personalization". The upshot: there's a lot more information in the moment that's relevant to purchase logic than in a person's profile or market demographics. Advertisers/shoppers could avoid massive amounts of creep factor by focusing on this, probably with vastly superior conversion factors.

The final thought: advertising is well and good, but where the rubber hits the road is in making the sale. Which is where Amazon (and other sales-oriented sites: eBay, Craigslist, Apple's iTunes) wins all over any advertising-based site.

Update: oh, and the email I sent to Pearson? It bounced. I'm shocked, shocked ....
