Ever get lost navigating the treacherous and vast waters of online communities? This handy Map of Online Communities gives you the 411 in most awesome fashion (link courtesy of Kottke.org). Regions and countries are sized in approximation of their actual community/membership size.
I think I spend most of my time in the countries surrounding the Sea of Culture (which is sadly ironic in and of itself), but would really enjoy some wreck diving at the shipwreck of the SS Howard Dean (just east of Huffington Post island). Enjoy!
