What is a “closed” question? How do they work?
What's the difference between closed and not closed question on SO (except taged as closed of course). When you look at it, one can still down/up vote, add answers, add comments and so on. So what's the difference. In my opinion if question is closed there should be no activities allowed on this question (adding comments, answers, down/up voting etc) except for reopening. Otherwise it works like some sort of dummy to me.
