Data Portability seems to be a hot topic this week with Facebook Connect, MySpace Data Portability and Google Friend Connect, each letting their respective users to share their data over to other web sites.

Facebook Connect

Today we are announcing Facebook Connect. Facebook Connect is the next iteration of Facebook Platform that allows users to “connect” their Facebook identity, friends and privacy to any site. This will now enable third party websites to implement and offer even more features of Facebook Platform off of Facebook – similar to features available to third party applications today on Facebook.

MySpace Data Portability 

MySpace, the world’s most popular social network, alongside Yahoo!, eBay, Photobucket, and Twitter, today announced the launch of the MySpace ‘Data Availability’ initiative, a ground-breaking offering to empower the global MySpace community to share their public profile data to websites of their choice throughout the Internet. Today’s announcement throws open the doors to traditionally closed networks by putting users in the driver’s seat of their data and Web identity. The launch of the Data Availability initiative marks the first time that a social Website has enabled its community to dynamically share public profile information with other sites.

Google’s “Friend Connect”

Websites that are not social networks may still want to be social — and now they can be, easily. With Google Friend Connect (see http://www.google.com/friendconnect following this evening’s Campfire One), any website owner can add a snippet of code to his or her site and get social features up and running immediately without programming — picking and choosing from built-in functionality like user registration, invitations, members gallery, message posting, and reviews, as well as third-party applications built by the OpenSocial developer community.

The idea sounds good but we gotta wait till its actually implemented.
