The Dirty Dungeon adventure generation method

I'm kind of enthralled by this idea, the Dirty Dungeon, for how to generate a dungeon adventure based on  maximum input from the players. It amounts to a coordinated brainstorming session with rewards for submitting ideas. But it also gives you chance to use skills for research and history that often don't get used in a game session. And it's built around the solidly practical idea that adventurers might want to research a dungeon before they head off into it.

Picture is from yet another automatic dungeon generator, one that gives you suggested contents for the dungeon as well as a map; I liked this one a lot.
