I see that there are some old highly voted questions that, to a very critical eye, would not be considered appropriate according to the current rules for good questions.
This question for example asks
What's the best framework for creating mock objects in Java? Why? What are the pros and cons of each framework?
What is the best seems subjective. Asking for a list with pros and cons seems open ended. Would this question be considered appropriate if it were asked today rather than 3 years ago?
Should such questions be closed? If so, I think they should have a banner at the top that explains that, although the question was once considered appropriate, it should not be emulated. Perhaps such questions should be set to a vot of -1, so better questions are pushed up the lists by viotes? Although that should be done in a manner that does no peanlize the reputation of the poster. This would presumably need a change to the interface used by the moderators.
