)arrow If you haven’t, make sure to check out this idea: StumbleUpon is a – free – tool that lets you browse, review and share great webpages. It lets you select categories as a way of refining your tastes and interests, and tailors its results to you. You can associate with people sharing those tastes for even better results. When you find a page you really like, voting for it is as easy as a click; if the page hasn’t been reviewed by a StumbleUpon user yet, you can write the first review.
StumbleUpon installs itself as a little toolbar in your browser. If you are ever bored on the web, click the Stumble! button and a random site matching your interests will appear. I’ve found absolute gems this way, it’s totally addictive! Read the Wikipedia definition.
