I've seen before where some questions get closed as duplicates of unanswered(or even closed) questions. Is this behavior that should be encouraged?
For instance, there has been a few times where I was going to ask a question and found a similar question beforehand. The similar question had no good answers for me, but I didn't create a new question because I knew it'd get closed as a duplicate. Even if my question was more specific, it was still related enough to be considered a duplicate(even though mine may be more easy to answer due to additional info.)
What do you think? Should asking unanswered questions be OK and not closed as duplicates? Or should we encourage bumping the unanswered question instead or something similar?
Also, some of these questions are so old as to be irrelevant to now. For instance, if a question from 2008 was posted as "What is the best way of dropping this and using jQuery?" back in 2008, a plugin may not have existed that now does. So the good answer of "Try the jQuery plugin Drop-jQuery-and-try-jQuery" will not have been posted. And even if it is bumped, then a person that knows about this plugin may not put it as an answer because the answer is so old as to not matter to the asker now.
