www.digg.com Its a tech news aggregator with a social networking twist. Users link to stories and other users can "digg" the story. If it get dugg enough it moves to the front page.
Recently I found this site that memorializes old Ma Bell and even has a link to a free online book that was written in 1984 about the split up of AT&T. Interesting read and many of the predictions have and continue to come true.
