Scott Jangro's Bumpzee is really catching on, and I'm a big fan. It's been around for about a month now, and its a great blog community that is part digg, part linkedin, and part MySpace. When I joined about 3 weeks ago there were only about 25 other members and that number has already grown to more than 150. The coolest part for me is when 2 people add each other as friends you can view each other's contact information - in an industry that is built on relationships, being able to stay in touch with the important folks in our industry is key.
