I'd just like to put forth my own Abridged History (http://www.obsidianportal.com/campaign/the-10th-age) as a possible candidate. I've been revamping the site with graphics (gasp!) and have been steadily expanding the world content to include many topics, from common drinks and breeds of tobacco to various rituals practiced upon death. My header graphic is a tad big, using the full 700x300 pix but such is the world.
Anyway, thanks for the consideration!
