I made some changes to the blog over the holiday, including adding support for entry tags. As a result, it will be necessary to re-subscribe to the RSS feed. I am now handling my RSS feeds through Feedburner, so in the future if I make changes it won't be necessary to change subscriptions. Here is the new RSS feed. Please let me know if you notice any funkiness with the website.
There will most likely be additional changes soon. Movable Type 4 is in testing, but from what I have seen so far, I will make the jump when it is out of beta.
