Perhaps. That's assuming they make friend lists accessible.

   As it stands, everytime you do a quiz or whatever, your friends
   lists goes "out", away from the walled garden. Corporations know
   who your friends are now. Advertisers know. Politicians know.
   The connections will live but they'll be transformed, morphed,
   transmogrified, combined in myriad ways like shredding millions
   of phone books and taping together random names until the
   initial network connections are blurred with other combinations.

   At any point in time, FB can easily shut off its social graph
   experiment. *poof*, walled garden again. The option to export
   friends has ALREADY been shut down at least TWICE that i know of
   on Facebook; scripts running on older versions of their API no
   longer function.

   Google is the same way. They change the API, change the rules,
   change the ability to access it.

   Myspace obliterated theirs, even though Myspace is still
   technically around.

   I'm not impressed by 'a billion". It could be all 7 billion and
   the babies too.

   With people having multiple accounts (I have two or three I
   think, but I know people with 12 or more FB accounts), the
   "billion" is likely an exaggeration, and I suspect the true
   number is less than that.

   I mean I could be wrong; perhaps 998,000,000 users all have a
   single account. But, like with any boastful leader talking about
   how wonderful his country is.. in this case, the country of
   Facebook, my skeptical flags automatically go up.
