Folklore and the story of the Mac
Folklore is a new CMS devoted to collective historical storytelling. It's written in Python and will be licensed under the GPL.
But that's not the only reason why it's interesting: The first project it hosts is about Apple and the Mac. It's full of first hand stories and anecdotes about the development of the Macintosh, and the people who created it. It's very interesting to see how the Mac interface was designed, for example: Busy Being Born.
Oh, and it also has a RSS feed.
