The Vana'diel CensusDQ reader Matt Teets sent me a link to something I'd never seen before: the sixth annual Vana'diel Census.
It's a census of the Final Fantasty XI online community. You'll find information on login distribution by hour of the day, login time per character, job level distribution ("job levels" refer to character level), character distribution, racial distribution of character, rare item acquisition--and that's just scratching the surface, really. It's extremely well-presented and very interesting, even if you don't play the game. Here's the link.
