A reader of Google Blogoscoped reveals that Google briefly posted a “confidential” video detailing its plans to compete with Facebook.
Google’s recent big social effort is called Mocha-Mocha (or Mocka-Mocka?), and will become the infrastructure for all social stuff across all of their applications. As a part of this, a new feature called Activity Streams will be introduced or at least implemented in Reader this quarter. This will be comparable to Facebook’s News Feed (Minifeed?) feature, and integrate Gmail’s addressbook and contact list.
