OK. Call me a big 'ol geek, but I think this is really cool. If you're using MSN Messenger (WebTV Messenger, Windows Messenger or whatever they're calling it these days!) , here's a neat little way to know when my weblog is updated:
1) Add "email@example.com" as a contact.
2) Start a chat with "firstname.lastname@example.org" and enter "add http://www.kevindonahue.com/kevin/mt/"
3) The end.
If you're signed in when I update the blog, you'll get a little pop-up telling you I updated and the title of the post. Cool!
