Philippe-Antoine "Chatty DM" Ménard and Michael "Chgowiz" Shorten have released the One-Page Dungeon Codex 2009 and One-Page Dungeon Compendium for download. These are early "hobbyist" versions of the PDF; they plan to do a much fancier version soon. All of the PDFs are free, although I believe they will be offering print versions for a low price as well via one of the print-on-demand services.
My one-page entry, Shrine of the Savage Jungle, is in there (page 34) as an honorable mention of Best Dungeon Crawl. There's a lot of interesting stuff in there, and not just dungeons; there's a "One-Page Dungeon Manifesto" by Santiago Luis Oria that I agree with 100%. In fact, I swear, right here, right now, to make the improvised kingdom and wilderness supplement I've been planning to fit into the one-page philosophy: the goal of The Nine and Thirty Kingdoms will be to describe the entire region on one page, each kingdom on one page, and each habitation on one page.
