200 Million Plus 1

I read in the paper that Facebook recently signed up its 200 millionth account—I’m pretty sure that was me! Yes, I finally succumbed, so, here I am using “friend” as a verb: please friend me! And please forgive my lack of knowledge of Facebook etiquette…if you write on my wall, should I immediately go write on yours? Is sending a message the equivalent of passing notes in class? How many friends do I need to feel “popular”? Is it even "cool" to ask people to friend me?? Should I just go find the drama geeks right now?
