Facebook is my favorite social network. Back in 4th quarter 2008, I decided to use Facebook exclusively as my personal business and social network. It was a conscious decision to use their site for business not just social things. I picked them over the more business oriented networks like Linked In and Plaxo because I wanted the personal side to all my "friends." I want to know if their life revolves around their dog, or what is going on with their family. I want to spend time getting to know my Facebook friends as real friends, not merely people I'm "Linked In" to.
FrontGate Media does social networking, so we will exist in all the social networking worlds, working on Fan Development in each one. However, I personally am only putting time into Facebook as my own personal page. That doesn't include niche networks like CCAS, but in terms of the big global networks, Facebook is where I'm spending my time.
