Why when someone retags a question (and also when he or she suggests an edit, I think) that question becomes the first in the list of 'active' questions???
This is very inconvenient — I hate it — because it puts back questions that are really active (with new answers, for example). Retagging doesn't sufficiently change a question to put it in the first position. The list of active questions should be reserved for questions containing real changes rather than minor, irrelevant changes such as one more or one less tag.
This wasn't a problem for me until certain user started to retag questions permanently. For example, in the last two hours he has made 16 suggestions or editions (and often the number is even larger). I'm not against his editions or suggestions, I am against the questions he edits appear in the first position in the list of active question.
