You're not missing anything unless you like everyone in the world pestering you to be a face book friend, then your information is up for grabs to anyone that wants to take the time and effort to hack your account. I know some will tell me that can't happen but it has, and I already get enough spammers and phishers due to my wife's web site which I administer and built. They still find our addresses and I get the junk to deal with from all over the world.
That's the main reason I'm not joining in on the ornament exchange. I'd really like to but the risk of more junk turns me off. So If I want to send someone a gift I will but it'll be privately.
OK Back to Charlie!
