The reason is that it's not a blog entry. It's the "read in a browser" version of Patrick's amazing email course. Lots of people signed up for it when it was new, and even though Patrick specifically asked that it not be submitted here, every mail was. Now we get the occasional repost from people who are just now working their way through the course. That it is occasionally updated and has no date stamp should therefore not come as a surprise.
