Google Social Search launched

Social Search, previously announced by Google, as an experiment, lost its beta status and became a full-fledged project of the company.
This service is intended for issuing in the first lines to requests for information published by people from your circle. Thus, Google gives you the opportunity to see what your friends and acquaintances are writing on the web, publishing them in Gtalk, Google Reader, Flickr, Picassa, Twitter, Facebook and other social sites.
To work in Social Search, the user must have a Google Account, Google Profile and add users to the Google Contacts list.
Currently this service is not available for Russian users.
