Obviously they spread. I guess my use of "meme" was a bit too broad, I meant image macro, specifically. They used to be humorous, but they're now so overdone and generic that they simply hurt to look at. It's like a fast food five second dose of "comedy", which I guess is fitting for our present fast food society.
Now that I think about it, that statement was asinine. I'm quite familiar with 4chan, Something Awful and Reddit. Never underestimate the stupidity of a general community. But sometimes, I just wish people would take the time to watch a 64k demo instead of a YouTube celebrity video.
Clearly you are unfamiliar with the basic properties of Internet memes. :P
