What is the endorsed way of requesting updated answers to an old question?
Say I'd like to know the best GUI application for some command line tool. Of course this question already exists and has an accepted answer dating of two years ago. Since then new applications have seen the light and are maybe also featured in some comments or answers, but I'm not sure that their votes have catched up because old questions don't get that much attention.
Should I just ask a new question pointing out that I consider the duplicate question stale?
There's another question where the answer suggests that the mechanism for keeping answers up to date is downvoting older and upvoting newer answers. I don't have the impression that this mechanism really works for all types of questions.
