I use SO all the time for gleaning information from the answers, but never for asking questions, for this very reason. The questions that show up in search results are full of great answers and information, but mine ended up full of people who didn't know the answer to my question but were eager to tell me about something they did know. Then I'd put more and more effort into providing context and justifying the question, until eventually the answers dried up. I decided I was better off seeking help on mailing lists, issue trackers, chat rooms, etc.

Yeah honestly I feel like it has gotten a lot worse since I was using it actively maybe 8-10 years ago. It seems to have moved towards a lot of people playing the karma game, and trying to focus on every flaw rather than trying to answer the question and give help. Nowadays, I usually try to find a community or forum directly related to the specific subject I'm working on.

However, it's hard to tell if the quality has actually changed, or whether it's just more geared towards novice programmers and I'm just not asking the type of questions that get help on the platform anymore.
