I’ve just SIOC enabled this blog using the SIOC Exporter for WordPress by Uldis Bojars.  Quoting from the SIOC project web site:

The SIOC initiative (Semantically-Interlinked Online Communities) aims to enable the integration of online community information. SIOC provides a Semantic Web ontology for representing rich data from the Social Web in RDF.

This means you can explore the blog as an RDF Graph including this post.
