So, I am sure everyone here is just a bit more facebook savvy then me, but here's a little hint.
I would go right now, and change all your Privacy settings to Friends Only. (Under Account, Privacy Settings.)
Of course, everyone's favorite game to play pre-production is internet the cast - well we were facebooking a new cast member, and I had all this information the rest of the team didn't have - why? He was a friend of a friend. Now, I got the drunk pictures, info, everything.
But made me think, in this world of people just being one degree of separation, it might be nice to turn up the privacy, or maybe just step away from facebook entirely.
