The case is the following:
1) I went to the SU and moved to the last page of the questions list. I selected this old unanswered question from the last page http://superuser.com/questions/6407/how-can-i-remote-desktop-from-windows-xp-into-windows-vista and voted for it
2) Then I click on Questions tab and checked Hot and Active... It doesn't appear on either of them. And it was not in the Newest too.
So, my question is does Voting for a really old question can bring any attention of community to it?
Or it was initially supposed that only author can reanimate the question (by editing it or assigning a bounty). And also a user with 500 score can retag questions, that seems to be similar to Edit and also will move the question on top of the stack.
What I suppose that Active questions should be ordered, taking into account any kind of activity - comments, voting, putting a favorite start, edit, retag and so on...
