Facebook just blocked me from sending Friend requests
Because I made 3-4 that were out of my circle of friends.
Facebook moreover seems like just a place to circle jerk with your circle of friends. They've done a real good job recently of taking counter measures against spam but it prevents me from seeking out new people.
I miss the days of myspace where I'd type in an age range, an area code, and females only and get a list of girls and start hitting up on them. I made a lot of friends and met lots of girls that way...
It was easy to remove mistakes on myspace, FB not so much as it connects to you more directly. They've got such a stronghold it doesn't really matter anymore.
