As a moderator, I can close a question unilaterally. I've been trying not to do this, because I think it's unfair to let one person decide whether a question should be closed. However, there are very few users who are inclined to cast close votes even for slam dunk cases, and so many posts that should be closed will languish with between 2-3 close votes.
What should the moderator policy be on such cases ? Again, referring back to the earlier discussion about edits, I would prefer to ignore such matters except for the idea that in this beta phase we'd like to keep a clean front page.
