thinking the current bulk of users of facebook never heard of a myspace. they are the slow adopters forced into it through the social thing when they got their first ipod to keep up with their kids. parents and grandparents and teachers, they are not technology people, they just followed along and now they are stuck.
the people who are real movers have already left facebook in concept and are on to other social systems entirely.
google+ is the far better alternative to facebook in every way for the few of us who actually know, care, understand. Those few do not make much for a success story.
