StumbleUpon: stumble your way across the net

There are a lot of "community browsing" services out there ; essentially, you highlight which pages you like, and it starts showing you other pages you may like. Delicious falls under this category as well, though at a slight tangent. The one I like the most is StumbleUpon; and not that it means it will be as big, but is backed by the same guy who backed Google (ok I agree that's a lame statement to put in there, but then again Ram Shriram's name does put a lot of clout to a new venture)

You get a toolbar installed, select the topics you would like to have in your stumbling and then just stumble! The thing about these services that you want is really the quality of recommendations; I get 1 in 4 pages which are read-worthy and 1 in 10-15 which are great, and that's a pretty good ratio. Many of the services that I write about on this blog are discovered through SU. And the Google integration is great

How does it make money - well for one, it directly asks companies to let their webpages get shown during a user's stumbling so its a nice monetizing that way and then they have premium customers though honestly I cant see many people converting
