UnderConsideration: The Design Encyclopedia

Speak Up, Brand New and Quipsologies are all by Underconsideration. Another gem they're responsible for is the design encyclopedia, a project powered by DocuWiki. It's too much to describe here, you just have to check it out. To say it's a valuable resource is a huge understatement. And because it's a Wiki, it's also a living, breathing document. Enjoy.
