That's funny, I would have said that a lack of moderation in favor of being more "welcoming" was a big part of what ails the site. Seems like it's been overrun with "write my regex for me" kind of questions.
At the time I would answer to others. Now I don't really bother. I often see a wrong answer being marked as correct, because it came before an actually good answer.
For me SO now is at most a website where to copy boilerplate stuff like "how to create a unix server socket".
