At least the sample size of two that I live with who responded to the question{aire}. Last week after it was announced that Facebook, long the exclusive territory of those with an edu email address was going to throw open their doors to everyone. There had been an intermediate stop that allowed employees of certain corporations in and the addition of geographic networks to the existing school networks. When I mentioned that to my two teenage sons they exchanged the "Mom has no idea what she is talking about" look followed by the proverbial "how do YOU know?" question. I smiled and told them they could just wait and see.
