The thing is, different parts of the internet have different memes. What kinda memes are we talkin about here? I know of dat boi through tumblr, but I'm sure reddit and 4chan have heart of it. But what about my jorts, jirt, and junglasses? Loss.jpg? Starter packs or tag yourself? "I fired, and then I missed. And then I fired again. And I missed."? The History of Japan video? Anything made by Bill Wurtz? Hell, you can argue Serebii Forums could have it's own memes. (e.g. The Bedrock, the haunting memories of Your Banned, etc.) How old are we meming? Are we classical meming or only memes from the past two months?
Memes are a huge thing that spans an entire internet. It is a beautiful example of contagious diffusion, but because memes are so fluid and ever changing, you definitely need some major rules and guidelines on that puppy.
