In the 90s it had that, mostly because there was a negative feedback mechanism for poorly thought-out questions. If you posted a question on usenet or IRC that obviously demonstrated you hadn't bothered to invest any effort into reading or trying to solve the problem yourself first, you were flamed.

Over time, as a more general populace joined the Internet, the ethos changed to act more as a support system rather than the more demanding expectations of the past. Presumably that was due to a recognition that newbs did not have the exposure to computing or tech that the prior generations of users had and so the intent was to be more educative so that these new users could learn to solve things for themselves. Alas, that optimism was misplaced as the majority of people are not interested in thinking for themselves but instead just looking to follow a checklist with no understanding.

If you've ever had to deal with customer problem reports, you'll know that isn't just people using SO and related sites.

Yeah, as someone who has to deal with bugs from systems layer to userspace, a non-trivial chunk of reports (not from customers per se) are: "crap blows up, please figure out".

FWIW, some four years ago I wrote this for this "bug filing recommendations"[1] guide for the OpenStack community when triaging lots of bugs.

In my experience, the most and informative and delightful bug reports I've ever come across are from Japanese customers. And obviously, I prioritize those bugs that are competently written.

My most common from end users is, "it won't let me..."

It won't let me login. It won't let me change my profile. It won't let me go to the page I want.

Such a waste of time. Two seconds of thought should allow anyone to realize that is not enough data for me to even begin troubleshooting your problem.
