"Digg is a news website with an emphasis on technology and science articles. It combines social bookmarking, blogging, and syndication with a form of non-hierarchical, democratic editorial control. News stories and websites are submitted by users, and then promoted to the front page through a user-based ranking system. This differs from the hierarchical editorial system that many other news sites employ."
I check this RSS feed from this page several times a day. The main emphasis of this site is Technology news, but they've recently expanded their Digg news to Entertainment, Sports, Science as well as a few others. Very cool site, check it out HERE. Digg is pretty popular for those of us that dig Tech stuff. Digg is also the first of its kind to evolve what is being deemed at social bookmarking/networking. If you like Digg and have iTunes, subscribe to Diggnation (a video podcast) via an iTunes subscription. Diggnation talks about the most popular and/or oddest stories from Digg. The hosts are a couple of young guys who swear and drink beer during the video; great stuff.
