data portability and social connections seem to be the latest trend on the web.

Google has just announced friendconnect:

Websites that are not social networks may still want to be social, 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.

Facebook has announced 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 has announced Data Availability:

A new way for users to dynamically share their user generated content and data with websites of their choosing. The Data Availability initiative is founded first and foremost on the simple and comprehensive user control of their own content and data—users will have control over what information they share and who they share it with.
