Are Google and Facebook splintering the social web?
I think we are seeing a trend right now towards empowering users to have granular controls over types of information they share or information about them that is shared. It’s a sign that companies like Facebook and Google are competing on privacy.
Facebook is in the process of rolling out a sweeping series of changes to the way users can control their profiles and content-sharing on the massive social network. Among other things, the changes allow users to selectively share status updates or content with certain groups of friends, just as Google+ introduced the idea of Circles, which allow users of that network to segregate the people they follow into specific groups.
