StumbleUpon: The best thing that has ever wasted my time.

StumbleUpon is neat: I click a button, and it randomly finds a page that includes one or more of my favorite topics. The number of my bookmarks has at least doubled since I started using it almost a fortnight ago. A FORTNIGHT!

Setting it up is simple, especially if you have the Firefox browser. Simply go to the StumbleUpon extention page and the download the extention, and then enter a username, city, age, gender, and the email address (at the bottom of the page) to send the password info to. Don't worry, there's no chance of spam or spyware. Don't forget to check the boxes of the things you like.
If you are an Internet Explorer user, you can the the IE StumbleUpon toolbar instead, if you want.

Once that step is done, you can click on "Stumble!" and start tripping around the 'net. You'll most likely visit some sites you've visited before, but don't worry, keep stumbling. Don't forget to click on the "I like it!" and "Not-for-me" buttons to train StumbleUpon according to your interests and other like-minded people.

Like I've been saying, I'm hooked. And if you find a site that others might like, don't forget to blog it.
