The social web is booming, signing up new users and generating new pieces of unique content at a steady clip. A recurring theme of the social web is "data portability," the ability to change providers without leaving behind accumulated contacts and content. Most nodes of the social web agree data portability is a good thing, but the exact process of authentication, authorization, and transport of a given user and his or her data is still up in the air. In this post I will take a deeper look at the current best practices of the social Web from the point of view of its major data hubs. We will take a detailed look at the right and wrong ways to request user data from social hubs large and small, and outline some action items for developers and business people interested in data portability and interoperability done right.
