Meebo Announces XAuth

On Monday Meebo announced something called XAuth (not to be confused with the X Windows authorization program). What is it? It’s a small JavaScript library intended to be used by website developers to tailor a web page to a specific user, with the end goal of creating a better user experience.

One of the stronger use cases in my mind is:

  1. You’re logged into Facebook, but you never use Twitter
  2. You read a news article on
  3. The News & Observer website could intelligently decide to show you a “share this on Facebook” button (because you use Facebook), and could decide not to show you a “Tweet This” button (because you don’t use Twitter)

The specification allows more flexibility than that. Website operators decide what information to share, and users are able to opt-out entirely.
