If anyone is looking for more technology along these lines, you can search for "blog aggregators". One that I've used under linux is "Aggrekator". I used it quite a bit until I found something better to do.
Typically, these packages can pull from any website that has an RSS feed. So, blogs, tmuscle (or whatever it is called today), CNN, etc., etc. Some web browsers are nice enough to show a little icon in the corner of their display when a website provides an RSS feed.
