Scapegoats and bond building

Friendship is all about two people looking in the same direction. The same thing is said about love in fact. Looking at one another ends up to be quite boring and once you've finished reviewing the pretty details you'll pass on to the not so pretty ones. So the best is to look in the same direction.
Sometimes its all about sharing a real interest in a same subject or simply working together on a same topic. But most times, it seems to me, bonds are built by having a common scapegoat. Team spirit thrives when everybody starts complaining about a same person. There is nothing really glorious about it but if you want to bond quickly wih someone else start criticising somebody that this someone else can't stand. Within minutes you'll be just so close and have so much to share...
Today facebook is all about you declaring you know others and then its all about standing all together and poking one another or hoping that somebody will state he has a secret crush on you... there is a bit of biting and racing but by the end of the day are you any closer to the rest of your friendly herd? I have the impression that it is all rather static in fact because it stays artificial. So how long till people tire from facebook if no real bonding takes place...
So I wonder whether facebook won't soon seriously go down the "scapegoat" path because it is a rapid bond builder and may bring some dynamics to it all...
