Matt Webb is a real Renaissance geek, and as such he's too busy to actually read the great and defining works fo the Renaissance, such as DaVinci's imposing 1,565-page Notebooks. At least not all in one gulp. So Matt's poured all of the Notebooks (scarfed from the Project Gutenberg site) into a script that sends out one page a day as RSS. This is not unlike Phil Gyford's Page-a-Day-Pepys'-Diary thing.
