Bloglines apparently doesn't like this feed:
Bloglines has encountered an error trying to fetch the latest version of this feed. Bloglines handles errors automatically, no action is required by you. The error was: The feed does not appear to exist. This can be caused by the feed URL being incorrect, or it can be caused by a configuration issue with the server hosting the feed. If this error continues, you should check the feed URL and, if it is wrong, subscribe to the correct URL.
Google Reader and Safari's built-in reader are happy with it---any suggestions?
