It's more than just meeting your friends' friends. Maybe there's a friend of one of your friends' friends that you'd get along with? Or for us single people, there might be someone 5 degrees away from us through one of our friends that we could start a relationship with. It's all about networking. If anything, it's neat to just see who you're connected to. <shrug>

There aren't any chat rooms, it's all testimonials, bulletin board postings and one-on-one conversations.
