Who uses Stumble Upon? If you've never heard of it, Are you crazy? If you get bored easily it's very useful to keep out of boredom. To the people that use it, what topics do you stumble on?
I used it for imgtags, and I use it sometimes. I dont like stumble everything, and use it all the time. I prefer digg.
Actually, you choose a topic and click stumble. Then it takes you ti any site listed under that category. What is del.icio.us by the way?
From what I've read digg and del.icio.us have pages that other people liked. When you use stumble upon, you can find new sites. The pages you find don't necessarily have to be bookmarked by other people. It's good if you're the type of person that usually clicks on the "digg" button on pages.
