The biggest problem with SO seems to be moderators stuffing around with the questions. "This is a bad question" (so I'm deleting it). "This belongs elsewhere" (so I'm deleting it). "I don't like the way you asked this question" (so I'm rewriting your 'how to do X' question to ask 'why is Y bad').
Thing is, people ask those questions in that way because it reflects how they think about the problem. Other people who think about it the same way won't be able to find an answer because the self-absorbed twits haven't figured out that if you asked a specific question, that's the one you need answered - not something random! As for deleting questions - FFS. Link to an existing one sure. But deleting questions doesn't help anyone.

As for the original question: Something is rotten somewhere. Ask a silly simple question you get slammed. Ask a detailed question with lots of information, no-one answers because it's too long or too hard.
