InformedNetworker is a social news network site modeled after Digg (but officially using the Digg-clone application Pligg) for those working in the computer industries. It covers a wide variety of topics including industry news, development, software, hardware, security, storage, servers, internet, etc. It tags and categorizes stories, and lists out the most popular stories of the day. It also has a section for reader comments on stories, which probably adds value and interest to those working in the industry (i would imagine that many stories of new products and technology generate lots of gossip and tidbits that networking professionals want to discuss).
