I have been finding SO much less useful recently (6 months). My primary background is in javascript and I occasionally pop on and look for questions to answer to help other folks out. However, I find most of the questions being asked not necessarily being questions, but more statements. Among the actual questions, they are more about this jquery plugin or that ASP.net thing. I wish that SO had better enforcement of how questions are submitted, along with quality.

My other problem at the moment is that I am working on some objective-c stuff and SO is mostly useless for finding answers. Being new to the language and the APIs, I am sometimes lost and trying to get my bearings. A few questions I've submitted have either been closed or ignored. Only one really got a good answer, and when I tracked down the author I found he is very skilled and helps out lots of people. But there only seem to be a few people like him.

And by the way, if you're in SF and know objective-c, I'll buy you a couple beers in exchange for walking me through a couple things.
