I don't think you're arguing against what I actually said.

> So would you argue that the Craigslist experience is only good for those with the "programmer's mentality"?

No, I think I was clear - I think the Craiglist experience is good for people who are familiar with simple sites like Craigslist, but not for all people. Craigslist has a very simple UX, so it would be hard to find someone who had trouble using it. It would be easy to find someone who finds the UX unpleasant, because I personally find it unpleasant because it's very ugly.

> Nothing, that's just it: you already know it. What you call "programmer's mentality" is actually fundamental to human cognition. In making sense of things we use what we've already made sense of. The more we can rely on our existing knowledge to figure something out, the less cognitive friction there will be.

Here, you're just agreeing with me, except that I didn't call the "programmer's mentality" the general rule of familiarity, it was the general rule that all things must behave according to the same rules.

> The cost of surprise can certainly be outweighed by other factors, or surprise in itself can be exploited to usefully convey something, but in my experience it is not generally used to these effects. For every zooming interface or slideshow where scrolljacking might make perfect sense there are hundreds where those three seconds of defied expectations are wasted to implement something that is either useless or entirely detrimental to usability.

I'm not claiming anywhere that it's impossible to make a bad UX, either by breaking previously known rules OR by following them, I'm claiming that good UX is context based and the rule of "scrolljacking is always bad" isn't true. You seem to agree with me here.

> Or I am the target audience and the designers have failed to design for the target audience. Or I am not the target audience only because the designer has failed to identify and characterize their target audience correctly. Or the designers primarily work with making business-required anti-features bearable. Or they're optimizing for first impressions and not long term usability. Or they're optimizing for generating more work opportunities ahead of themselves.

Sure, bad UX exists, and these are plausible reasons why it might happen. I never claimed that no UX ever was bad for any reason.

> To decidedly say that you, our user, is not our intended target audience seems like a conclusion that must be backed with a lot of data, something which IME not a lot of organizations can muster. From that perspective these alternatives seem more likely.

Here you're either misunderstanding me or knocking down a straw man. I didn't use the word 'decidedly', I said it 'might mean'. I also wasn't focused on the perspective of the organization or person creating a user experience, I was focusing on the person consuming it and criticizing it, without any regard for everyone else who also consumes it and whether they might agree that the UX is 'obviously' terrible.

To give a concrete example: Slack recently released a redesign, and I personally hate it and many of the interactions it created. Most people I know love it and had no issues adapting to the changes they made. Did Slack release a bad UX? I would argue no, even though I personally do not like the UX they created, because I think I am a rare case and for the majority of their userbase, they made the correct call and improved the experience. It seems to me that most arguments on HN about UX boil down to "I immediately closed the tab because it hijacked my scrolling, terrible UX." I'm saying that's a bad argument, and your personal enjoyment is not a complete picture of what makes an experience good or bad for the complete audience of users.
