My guess on this is that people will pretty readily accept it if it provides something valuable to them, something they can't really get without it. The amount of privacy that people have given up using internet tech is what leads me to believe that this will be no different. I remember when people were afraid to use their own names nearly anywhere. Then they began to post their real identities in facebook (and elsewhere) feeling that they could choose who viewed the information. Now people post their real identities, pictures of themselves and even their children on publicly viewable instagram accounts. This sticks out to me because I remember thinking in the past that there was some barrier between what people posted publicly vs privately in particular with regards to their children. Not everyone is so open but it is not something I hear discussed amongst my non-programmer friends and a large number of them share in this behavior.
