For the last few years, I've been running on a bogging platform that Brian wrote from scratch. It's been great. However, there's been a few things that I've wanted to do with the blog (like use Windows Live Writer), that it doesn't support. So in order to accomplish this I decided to switch over to using SubText so that I have lots of room to customize things and generally get myself into trouble.
SubText comes with a bunch of canned themes, and I picked this one mostly for the full-width text. If you hate it let me know, I may try out a few of them.
UPDATE: Bah, unfortunately I couldn't get the RSS stuff to map in a way that blog reader software would understand, so you'll need to re-subscribe to the RSS feed. Sorry about that.
