its not that everything has been discussed. far away from it
ES could use a lot of community ideas and feedback if we discussed threads insted of creating new ones
the problem is we have 10.000 threads that are pure spam, that push the real threads back to places no one looks at, and these spam threads are mainly flame wars.
proof of this is the ammount of threads that start with "i dont know if this has been talked about" or "i have an original idea [thats not original at all]", and then are answered by pure spam. thus making the forums monotone and people that in a few months post 4.000+ times OF COURSE are gonna get bored.
my suggestion is, use the search bar and revive old threads with smart ideas and a lot of answers.
