Their Q&A site was vastly better than what existed at the time, and that's how they won the market. Now, though, it is full of people looking for quick points (as you suggest) -- people that think that the original poster was asking for someone to search Google for 'em -- and I'm convinced that the truly helpful people have moved just given up.
One thing I've noticed, that drives me crazy, is people demanding more information in response to a question, without any intention of using that information to help find an answer. Their whole goal is to score points for asking more details. I don't mean to suggest that more details aren't useful, only that it isn't helpful in any way to ask for more information if you don't intend to follow up. (Perhaps that could be improved by allowing those sorts of requests to be sent privately, and without any chance of generating points?)
