Facebook Places - Serendipitous?

Last week in the lecutre, Luke talked about Facebook introducing their new application - Facebook Places.
It is a new application that allows people to meet up with each other by chance, or serendipity. You will "never miss another chance to connect when you happen to be at the same place at the same time."

I thought serendipity was supposed to be, you know, spontaneous, exciting, random?!
Even Dictionary.com states the definition of serendipity as "an aptitude for making desirable discoveries by accident." I feel these words fully describe what serendipity is meant to be. However, Facebook Places ruins it all because having the ability to know that your friend is down the road, doesn't make it serendipitous since it isn't a random (desirable) discovery.
Firstly, maybe your friend is at that certain place because s/he wants to be left alone. For example, your friend may be in the library studying for their exam that's coming up in a couple of hours, of course they don't want you to bother them!
Secondly, (as someone had mentioned in class) Facebook Places allows Facebook stalkers to be real stalkers.

But okay, it may be nice some times to know that your friends are at a particular bar/club/what have you and it's cool to meet up with them but you should at least have the ability to check yourself in, not have it automatically checked in for you. Facebook is assuming that we all want this feature in our lives and it's taking your "control" that you have over your profile away from you.

So, Facebook Places, serendipitous? No.
Facebook Places, sort of creepy? In my opinion, definitely.
