That pissed me off so many times that once the mods actucally got into an argument over whether my question should be allowed, that was the last time i ever posted or answered a question on SE. That being said that site is super helpful, i just wish they could make the moderators more tolerable. You would be surprised how many times a question is closed yet will have so many upvotes and answers.

Interestingly i have noticed that Quora has some nice thoughtful answers to tech questions, especially questions that have no shot in hell of being answered on SE.
