Sal is right. A while back, I read that successful blogs are updated very, very frequently. A very successful woman estimated that she adds content several hours per day.
Exactly how you "add content for several hours per day" and still manage time to do something worth blogging about, I have no idea.
The premise is sound, though. You usually need to add content frequently, in order to retain loyal readers.
Another thing I that I realized that I like about Jones' blog- He does not just write about himself. It's not all "me, me, me". He writes stories about his environment. The house, the dock, the characters. It's fresh because people (and their boats) go, and new ones enter the scene. Now he's added racing.
He does kind of violate the "frequent update" rule though. He doesn't write daily, yet he has loyal readers who wait around for the next outburst...err, update.
