blogToaster
Because you can never have too much notification of updates: Simon Fell’s blogToaster polls weblogs.com, and sends you a MSN/Windows Messenger message when it spots a blog you’ve added to your list.
In a self-serving-in-a-good-way way, when you check it out, you’ll need to add a blog to your list that will then update and ping weblogs.com fairly soon, and the only one you can count on is yours, so you might as well post a link to blogToaster while you are at it. Nifty.
Note that you do need to add exactly the url that the blog uses to ping weblogs.com – as in, find it there, and copy the link. Luckily, it only took me three tries to figure out what url I use for my own blog.
