Would you find it strenuous to tell your friends about if such a thing existed?
I've always had a thesis that I'm not sure is true, perhaps i'm not social enough, although I have my facebook friends and many contacts in my phone I really only talk to 3-8 people. If such a thing existed I don't even know if it would be too much work to switch since I would only tell that small amount of people.
But perhaps i'm too antisocial, I wonder what other people think about that.
