Map of Online Communities by XKCD.com which is very amusing. Some thoughts that this map brings to mind: How are there more people on Xanga than on LiveJournal? Are there really that many teenagers in the world? Who actually uses Windows Live? I wonder what a chart that showed all the overlapping memberships would look like... SourceForge totally belongs in the SE corner of the map, right where it is, in the Focus on the Web-Focus on the Intellectual area... how big of a geek am I that I knew that WoW was World of Warcraft? (thanks to Lisa and Roger, btw)
