Well, it's not really new - it came out a week ago - but I forgot to post about it before. The latest episode of the MediaWiki podcast "Between the Brackets" features Larry Sanger, co-founder (although he prefers the term "ex-founder") of Wikipedia. You can listen to it here:

He has a new book out now, "Essays on Free Knowledge: The Origins of Wikipedia and the New Politics of Knowledge", so mostly we talked about that, and his ideas about Wikipedia, bias, and so forth; but we also talked about the early days of MediaWiki, since Larry was around for all the initial development.
