I think it's funny that some posters want to protect the stars by giving initials rather than names.
I don't see the logic in it. If you want to gossip, then gossip.
There is no liability or defamation here. It's a posters opinion. If they're your friends, family and/or co-workers, then act like it and respect their privacy.
But if you're a a teacher from Utah or a sales clerk from Ohio, who are you protecting? Little clues to your opinions or to your specific knowledge is no more discreet than naming names, and it's just annoying.
