Admittedly I haven't used Facebook for a few years, but using it as a replacement for email would be social (+ time) suicide for me. Many of the most interesting relationships I've begun through the net occurred because of anonymity and a general lack of ad hominem. When someone is just a random handle then they call the shots on how much information is available about them online, and ad hominem is harder. It is a sort of natural human thing to be curious about other people, but it's funny how knowing more (in terms of facts) can make your more subject to your own prejudices. I am reminded by a quote from Werner Herzog "Truth is not the facts. Facts are norms. Truth is an illumination."

Then there is the whole time aspect: Facebook was engineered from the beginning to be a place where you spend time so it can display advertisements.
