I'm absolutely in love with StumbleUpon, as it has made the internet seem magical again to me! Wondrous things can be stumbled upon.
StumbleUpon allows its members to "like" interesting websites, and arranges them according to category. The premise is to share the best finds on the internet. As a member, you pick out the categories you're interested in, and StumbleUpon does its best to show you, in a randomized manner, the awesome things that others have found to be cool among the categories you're fascinated by.
It's mostly frowned upon to "like" your own site, though; I think it's kind of in bad taste.
