A beta version of The Django Book — a guide to the Web application development framework Django — is being released free online, chapter by chapter. OK, nothing new there; I think it’s now illegal in 38 states to write a book about technology without either blogging the writing of it or posting it under a General Public License. What’s interesting is the system that the authors have cooked up for allowing comments on every paragraph. It could get totally overwhelming, if not implemented just right, but I think they’ve implemented it just right. Sweet.
