I don't go on 4chan amidst the gayporn on /gif/ and /b/ and gore filled idiocy.
9Gag just takes everything and turns it to useless 'le' crap.
Reddit is meh.
FunnyJunk for me is a balance between OC and OP, people complain there but it's a whole lot better for me than other sites. The neutrality and history I have with FJ is what keeps me there.
