Really cool SIOC widget from Sindice (for WordPress)

I've installed the new Sindice SIOC widget, produced by Adam, Fabio and Giovanni from the Sindice team.

As you can see, if you look at the post author or click into any comments list, each user now has a speech bubble beside the username. Clicking on this bubble will show you posts, comments and topics created by that user across the "SIOC-o-sphere".

You can also click on any arrow icon beside a link in a blog post to see where else it has been referenced, like this one.

There is a Sindice SIOC API available which serves as a gateway to SIOC data via the Sindice discovery and search services, enabling the verification of the presence of a user or a link on the SIOC-o-sphere as indexed within Sindice.
