Well I think so far I've read five. It is annoying that they aren't listed in order, you have to search the page by the episode # (in one of the tags) and track them down manually like that. I realize he has skipped an episode or two but still it'd be nice if they had a page where they are listed in order for you to go through one after the other.
Still, it was a great way to spend my exercise time so that I got to read his blog without it cutting into my other activities!
