Oh wow, a 9gag thread that evolved into /b/ saying 9gag steals from /b/. What a fresh and original concept.
I go to 9gag, but I'm considering stopping and start using something like Funnyjunk. The thing is I couldn't be more sick of the "90's kids" crap, the "Twilight/Justin Bieber/Nicki Minaj/modern music sucks" crap, the "If you had this you're awesome" crap, the "TEH REECH DUNT PAY TAXES" crap. It's all just re-hashing of older concepts that, in the best scenario were funny the first time (and usually not even that). And no, not all Memesites are like that.
Before that I went to Memebase. I went there yesterday. It's like a shopping mall set for demolition. Reminded me of Google+.
4chan is just kind of silly. Angry people thinking that lots of swearing makes their point valid, and seeing gore makes you a big man. Then there's Anon posting links about how the republicans are idiots, how democrats are idiots, how everyone who doesn't agree with your political point of view is an idiot, and thinking that #Occupyeverything will somehow fix the world. It's like a kindergarten on steroids, really.
The only site I really like is xkcd, but I only have the pleasure of a new post 3 times a week.
