I have switched the blog to Google's blogger beta. Everything seems to work fine so far, but the site feed has a new address. You might want to update it in your news reader, since I'm not sure whether the old feed will continue to be updated (I will know after posting this).
UPDATE: Yep, the old feed still works.
UPDATE: The gmail-like system of search+label rocks! I just labeled all 911 posts of the blog in a few minutes right from the dashboard. Another great feature: no more waiting on the "publishing 34%" whenever you change your template or republish a post.
