Do you then conclude the same thing about Facebook, which has had a "real names" policy since basically forever?
"Facebook has always been based on a real-name culture. We think this leads to greater accountability and a safer and more trusted environment for our users." --Facebook spokesman Simon Axten, 2009
Is it possible that Google's social networking platform is following this principle for the same reason, and not because of some dastardly plan to build a dossier about you?
I still don't understand why Facebook gets a pass on this issue, when they have had a "real names" policy for much longer.
