StumbleUpon is a Web browser plugin and internet community that allows its users to discover and rate Web pages, photos, and videos. Web pages are presented when the user clicks the “Stumble!” button on the browser’s toolbar.
StumbleUpon chooses which new Web page 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. It is a recommendation system which uses peer and social-networking principles.Users can rate, or choose not to rate, any Web page with a thumbs up or thumbs down, and clicking the Stumble button resembles “channel-surfing” the Web.
eBay acquired StumbleUpon in May of 2007 for $75,000,000

Digg is a place for people to discover and share content across the web, from the biggest online destinations to the most obscure blog. Digg surfaces the best stuff as voted on by our users.
Every article submitted to Digg has a count of how many Diggs the story has received. You need to be signed-in to Digg a story. For every registered user that clicks “Digg it” the count goes up one. If a story reaches the tipping point, then it gets promoted to the homepage.
