countal.blogspot.com is my good friend (and frequently-abused personality on this blog) Alex's blog. He's going through his Worlds history for now. It's not nearly Jim-centric enough for my tastes yet, but I'm sure he'll get to it.
Idris Nolan has one at http://www.idris.org/ultimate. Idris always has seemed a little crazy on the frisbee field, but he really seems to be a sound thinker about the game, plus he's started a book club of sorts for the local scene.
Are there others? What's the competition like, not that this is a competition or anything? I saw a Pax Americana blog somewhere for some B- or C-level part-time Coed team, but can't remember right now.
