I'm now moderating a forum on IBM developerWorks:

A forum, moderated by Rob Crowther, to discuss building web pages and sites that are a part of the Semantic Web. We'll cover the main front-end technologies such as RDF, RDFa, Microformats, GRDDL and OWL. This is a community for us all to learn together about how to build the next generation of the Web.

If you have any questions about Semantic Web technologies, or just want to share your ideas, please come along and make a post.
