I don't think I can explain those reasons any better than he did.

There have been other instances in which people have asked a question that was generally thought to be not very good, but interesting answers came in. The fact that interesting answers come in doesn't imply that it was a good question, though. It could just mean that there are lots of interesting people round here, who at the slightest prompt will write interesting things.

Clearly it's disheartening when people vote your question down or vote to close. But it's certainly nothing personal: it's only a judgement on the question, not you.

I am referring to the "Do the empty set AND the entire set really need to be open?" thread (-> http://mathoverflow.net/questions/19243/do-the-empty-set-and-the-entire-set-really-need-to-be-open). I have seen there are already 3 votes to close, so I would like to ask what the reasons for these might be. Also, it seems there have been at least 3-4 downvotes, but no one cared to explain what for. As I see it, the thread had some interesting development, including the fact that it turns out that the 1st axiom is not merely of technical nature as some were saying in the beginning of the discussion. And the implications of omitting the 1st axiom seem (at least to me) not trivially pathological (i.e. such that we won´t be able to do any useful mathematics)...

Thanks in advance,
