I am cross posting a comment here that I posted on TC, this is an experiment to help me compare the reactions, sorry for the potential inconvenience. 2 things: A) Don't under estimate the power of software. It is obvious that I have full access right to my "friends" list, including data that my friends share with me. It is only a matter of time/need until easy tools to export this will be in the hands of users, power users firsts, casual users next B) Most users on facebook were rather computer illiterate at first ; we're talking about a population that basically is "discovering" the power of computers. They learn. They will leverage this knowledge to escape whatever walled garden emprison them, if only to do the cool thing that cool guys do. C) A flat list of friends is a very primitive way to describe social relationships, mixing strong ties with weak ties to the extreme ; this does not scale, this does not reflect the true and essential complexity of relationships. Focus will shift to more fine grained (and fluid) ways to describe relationships. D) The real issue is the single login one I think. I tend to believe that it makes sense that people will use their most "public" profile to login. That makes Facebook a strong contenter. But for quite some times, there will be services requiring an email address to login. Facebook (and Twitter) should better provide an email address soon, or else people will eventually become fluent enough to use a gmail one... Facebook is one big step in the evolution of Internet, but it is just a step. OK, not 2 things... that's serendipity I guess ;)
