My main gripe with it - are the closed questions. I think half the time I end up on SO - the questions is unanswered and closed. Delete the thread at least, why waste time of people searching for an answer to get frustrated by your over-zealous mods. Damn I hate when that happens. There were instances where the closed-unanswered question was the only place in the entire www where this was asked... :/
