Every site mentioned helps to create new memes and supports the "infrastructure" of motivating other to come up with new memes. The meme defense projects seems to try capitalizing from just popular memes by making them even more popular. YouTube,4chan,Reddit are like a complex network of indie music clubs. Meme Defender is acting like a major label, that just takes well known "scene" memes and exploiting them towards a non-meme audience. No wonder the "true fans" are screaming sell-out.
