An expernment

I am on Facebook but I keep my friends list small on purpose. I don't see the need for a gazillion "friends" since I am not promoting anything or live out of town. I post on peoples status, see what they have to rant about and invite people to a planned skating night. Anyway, I have 39 "friends" so I "poked" all of them to see how many would "poke" back. Some had a previous "poke" I had sent before so I could not do it. I did this on Sunday. I have received 5 back.
