A Map of Online Communities

This is fantastic! XCKD, which is a fantastic webcomic anyway, has posted a fantastic map-representation of the interwebs and all the various communites here. I'm not sure what my most favourite bits are - the treacherous river Bittorrrent? The Ocean of Subculture with the dangerous Viral Straits? Of course, being part of the Blogipeligo, I'm somewhat biased in that direction. (And? seriously, such a better name than blogosphere - I vote we change to calling it that instead /nods)Go look! It's wonderful :)
