Has Facebook made us socially retarded?

I'm sure you've all seen the thousands of "does he like me" questions on Y!A. What's gotten my attention is that most of these involve friending, poking, posting on somone's Facebook wall. It seems like a lot of the people out there are totally dependent on social networking sites to play matchmaker for them, and can't read emotion or have a face-to-face conversation anymore. This seems to be a problem even for people way past their teenage years. Is Facebook impeding people's ability to be social in real life?
