This functionality is not new to the users who have been using MySpace for quite a long time. In MySpace it already has this functionality for its users called “MySpace Data Availability”.

In facebook with the help of Connect, user will be able to visit other popular sites who are partner to Facebook and using the same login credentials they can the services that are offerred there and even can use the same set of networks, e.g. facebook users and their friends can virtually chat or digg news or can watch videos from one place and even can get updates also. Facebook users don’t have to login to those other sites outside of facebook to do some activities.
 

To achieve this the partner sites have to use the API(Application Programming Interface) from facebook to quickly integrate facebook into their system. Facebook has released the following key points for this feature-
 
Trusted Authentication- If you have a Facebook account then you don’t need to create another account in the partner site. Your facebook data will be ported in their siteeasily.

Real Identity- Extending as well as leveraging real identity in the Web as a trusted environment

Porting Friends list- Users can port their friends wherever they go.

Privacy- Users can follow the same privacy settings as they have setup in facebook while browsing those partner websites and can use throughout the web.

Real Time updates- Users can share actions or activities in the partner sites to their friends in facebook through feeds.

Presently Facebook has partnered with 24 popular web sites like Amiando, CBS.com, CNET, CollegeHumor, Disney-ABC Television Group, Evite, Flock, Hulu, Kongregate, Loopt, Plaxo, Radar, Red Bull, Seesmic, Socialthing!, StumbleUpon, The Insider, Twitter, Uber, Vimeo and Xobni. So, in near future we’ll expect all social sites will come under one place.
