Cool Tool of the day: StumbleUpon

http://www.stumbleupon.com/

StumbleUpon is a browser toolbar for Firefox or IE. It's almost like a cross between a social site, Digg, and Tivo. You specifiy what your interests are and click the StumbleUpon button and are presented with a random web site that it thinks you'll like. Like it? Click the thumbs up button. Hate it? Click the thumbs down button. It's that simple. Over time, you train the toolbar on what you like and don't like and it will gradually give you sites that you'll probably be interested in.
You can connect with friends, share sites with them, review sites, and recommend sites - and that's not all.
A time waster for sure, but a cool tool nonetheless.
