Popurls
Quote from Guy Kawasaki:
Popurls is a site that aggregates feeds from the likes of Digg, del.icio.us, Reddit, Flickr, Stumbleupon, Slashdot, Google News, ifilm, BoingBoing, Fark, etc (see very partial list in picture). This enables you to see, on one page, what much of the Internet is buzzing about—think of it as an Internet “dashboard.”
