Stumbleupon

Hey, StumbleUpon is a web browser plugin that allows its users to discover and rate webpages, photos, videos, and news articles. These webpages are typically presented when the user -- known within the community as a Stumbler -- clicks the "Stumble!" button on the browser's toolbar. StumbleUpon chooses which new webpage to display based on the user's ratings of previous pages, ratings by his/her friends, and by the ratings of users with similar interests. i.e. it is a recommendation system which uses peer and social networking principles. There is also one-click blogging built in as well. Users can rate, or choose not to rate, any webpage with a thumbs up or thumbs down, and clicking the Stumble button resembles "channel-surfing" the web. Toolbar versions exist for Firefox, Mozilla Application Suite and Internet Explorer.
It's a great tool to find new websites that interest you.

Yep, it's pretty good if you're bored. Just click stumble and see what random website you end up on.

I used that on one of my sites it was pretty cool.

I found some nice sites from it also.

Did you only just find that site lol? I tried the firefox plugin a while ago and hated it.
