It seems like some users make minor edits to old (and mostly) answered questions, editing things like tags, grammar and similar other minor details. So far this isn't bad and exactly what the edit function is for, but the problem I have is that it brings lots of attention to old and probably already solved questions and pushes newer questions down the stack where.
This practice is, to me, most noticeable done by C4 - Travis, but I have seen others doing this to, and at least I find this kind of annoying because in the last few days I happened to view more older questions than newer ones (maybe I just had bad luck). What is the general policy for this, should old and answered questions be left alone or pushed up to do minor edits on them?
Edit: To clarify this, I don't want to stop people from editing old posts! Old posts are likely to be found via google and thus should be accurate and correct so they can still help other people, so if someone stumbles upon an old answer and sees that the question or one of the answers is horrible wrong, I'm the last to say that an edit isn't encouraged. What bugs me is that some people seem to edit posts to get either badges and/or reputation (it seems like you get +2 rep on approved edits), and those are by no means good or needed edits (at least in my opinion)
