Following that question, which was marked as a duplicate by a some users (including myself), and the discussion in the comments, the OP expressed his feeling that his/her question differ enough not to be considered a duplicate.
This prompt me to ask whether there are/have been some discussion here about which policy should be taken?
I just came upon a similar discussion in the meta of scifi.SE.
Do we want to have clearer rules? Or just leave it to every user to decided for themselves? Do we want to have a strict duplicate policy (which could frustrate some users, or at least seem to)? Or we'd rather have a more relax policy (which might spread a lot the relevant answers)?
