It's hard to find but FR is an island in the Sea of Memes. This is his second Internet map, the first iirc was social sites by size. I think this one is by daily use (so Facebook is huge). I have pinged him as to why FR was an island in the sea of memes when it really belongs in The ocean of Opinion with Kos, Huff, Hot Air and American Thinker. xkcd is a web strip about math and science and other interesting topics. http://xkcd.com/802_large/
