As local memelord 'round these parts, I have one statement. Reddit≠Memes (but it's still pretty dank anywho)
Nope, memecenter is the best, there are so many graphics artist creating memes there. It is the largest meme site on the Internet not to mention there is a lot of original content there.
All of you think you know memes, yet you mention Reddit, Memecenter, Imgur, and 9Gag. Pfffffff, dirty commoners. 4chan is quite obviously the birthplace of half the memes in our universe.
