-Over the coming months, the boundaries between these networks will start to
-become indistinguishable as they all become part of your social circle.
+ Incoming data streams aren't limited to traditional social networks.
+They may include most any service which provides a syndication feed (both RSS
+and Atom). This allows you to view communications from friends in other
+diverse social networks - such as Diaspora, Google Buzz, and millions of
+blogs, news services, and other websites. You can also import
+contacts from (and write to) anybody that is accessible from your email
+INBOX and view them in your social stream. Over time we will try to
+build two-way bridges to other services so that you can freely
+interact in both directions with anybody on an accessible network that
+allows it.
