My direct answer to this months question of managing mixing work, friends, and family on Facebook is simple. I don’t mix them.
I lead a divided online life. I have my work life, SQL Server, Twitter friends, work friends, and work blogs that I follow. I also have a Facebook account that I use to follow and share things with my family and non-work friends. Sometimes they overlap a little, but for the most part I keep them separate. I am not Facebook friends with any one that I work with. I will sometimes share things about my work life on Facebook, but only if I think it will interest people (or I am trying to promote my blog.)
