"The possibility exists for a kind of mega-meta-source to emerge from Digg, where interesting news topics are associated with cataloged resources. But for that to actually work, someone has to manage those resources -- and that effort will take a level of humanpower and resources of another kind (the kind symbolized with "$") that RDF won't provide even the most ambitious sites just on its own."
See Digging RDFa. More news about RDFa is available at RDFa.info.
So I still haven't finished writing up everything that I've saw at WWW2008 but the overall messages were:
- RDFa is easy and gets people going with RDF quickly (see "They knew the train would come"). Semantic wikis (links to the Semantic Mediawiki project) have also come a long way to making it more err user friendly.
- HTML5 and the end of the browser development winter seems like the death to plugins at last. I hadn't realized this before, but the message seems to be that a plugin is a way of saying to the Web "your browser isn't full featured enough".
- The Facebooks of the world and all those online communities really are a danger to the Web - the creation of data silos. And I'd really like to have the time to write some SIOC plugins to help open up these silos (or just change my blog template to have RDFa).
