Vysr has announced support for OpenSocial applications via their RoamAbout browser plugin. This means you’ll be able to access any OpenSocial Web app no matter where you are online. This is all part of their User-Centric Web initiative.

The Site-centric Web confines users to individual sites in order to use specific apps and services, but the User-Centric Web breaks those barriers and allows users to access those very same apps and services from anywhere on the Web. You’re no longer chained to social networks, and can even communicate with your friends on those sites while somewhere else.

The RoamAbout plugin adds a small vertical row of icons for all of the applications and services that you want to access as you surf the Web. They don’t take up much space and provide a great deal of useful functionality and even some fun if you add some of the games that are available.
