Anybody else use StumbleUpon?

Discovered it last week. Very useful tool for finding articles. A sort of reverse search engine.

Basically you select your topics of interest and when set up click "stumble" and it will send you to a random web page related to those subjects. Click "like" on pages you especially like, "dislike" on those that are not relevant. It claims through this that the more you click the more they can streamline your interests so the more you use it the better it gets.

No, I never tried it myself. I see it around though.

I use Google News to parse thru news. I have it set to show things I like. Of course, I read the Ft. Worth paper and Minneapolis paper online for general (and local) news.
