I have family, folks from high school, folks from BYC, and folks from games.
I have unfriended some for being terribly crude (and you have to be pretty terrible to offend me) and some because they were only game friends and quit playing (or I quit playing).
I have to say, I have made some friends through games that I quite like, and same for some BYC peeps. Some are witty or silly and just appeal to me. Some have the same interests and we have a lot in common. I only joined FB because my sis encouraged me to, to reconnect with high school folks. She dropped fb and I'm still there!!
A high school friend organized a tribute for our former band director on facebook, and I'm really looking forward to it! All my favorite high school friends will be there, more so than the average reunion.
And a friend of a friend had a baby goat ER, and posted on facebook. I asked a friend (that I've never met) and she gave some good advice. So one friend I've never met was assisted by another friend I've never met, and had an answr within 10 minutes. I think that is REALLY COOL!!
Also, it's easier to post pics on fb than it is on here
And yes, I changed my privacy setting so they can't 'borrow' them....
