Are you on Facebook?, that's the question

I joined FB in 2006. At this moment I don't recall the impetus, whether it was my 'bright' idea or I was invited by a friend. The question on many people's lips is, Are you on Facebook yet?? Not everyone is. Some folks have even defected, particularly in reaction to privacy concerns. Back in Sept 2006 Danah Boyd wrote an interesting piece called "Facebook's "Privacy Trainwreck": Exposure, Invasion, and Drama." The fact remains that for many this social networking site presents an inviting and compelling online environment.
