I have used other forums of various kinds as well. One thing I've noticed is that they are much more useful when you are new to the topic. After you kind of learn what there is to be easily learned, then you notice the "bad" posts, you didn't pay attention to before. I think the solution is just to check in a bit less often, don't let the fluff deter you from asking or answering serious questions. If you're not doing so, check the other forums on here, not just the fixed gear one.
