Well it will remain in existence, but i've seen a drastic reduction in opinions in last one month. Earlier there used to be more than 15 responses to even the most trivial questions. Now people hardly get 4 or 5 good responses for questions. Opinions are only given on questions which generally do not help anybody.
I don't know I think 'how do I look' questions can still easily get about 40-50 replies as well as the 'critical questions' which trigger debates, I think most people just don't bother with answering trivial questions but then again they never really did..
