Yes my biggest pet peeve with Stack Overflow specifically is that instead of an answer to the question, you'll often see a lecture about how the poster is doing it wrong. Usually this is because the responder didn't actually read the question and is trying to get their internet points in before someone else answers it. It's not a bad idea to outline a different approach, but it's almost always better to first answer the question and then add your opinion afterwards. I've even seen questions where they poster will state "I'm not doing it the accepted way because..." and still see useless responses saying "You should do it this conventional way instead" etc. I think this is just a negative of having a points reward system that encourages answer sniping. However, without a points system you'd see far less content. I've accepted it as a necessary evil, and overall I'm pretty happy with the quality of SO content once you learn to filter out the nonsense.
