Did it ever occur to you that each time you open your feed reader, you're taking a trip not just around Azeroth (or whichever online world you're currently inhabiting), but also the real world?
Syl and Larísa recently had the idea of plotting bloggers' locations on a world map, as part of an exercise to see who blogs in a language other than their first. MMOmeltingpot took up the task and it seems it's now become a way to see how bloggers are distributed around the world.
You may or may not know, but I'm a huge map nerd and in fact, make them for a living (up until earlier this week, anyway! *cackle* Ahem.), so naturally I think this is an awesome idea. If you're a blogger and haven't seen it already, head over to MMOmeltingpot and show them your support.
