Brilliant post from Greg Gershman about distributing the ownership of structured data:
The answer, I think, is to continue to push forward with semantic web technologies, whether that's a big 'S' or a little 's'. The structured data needs to make its way out there, at the edges. Marc Canter's work with digital lifestyle aggregators and the coming of structured blogging to Wordpress/MovableType are all going to help in this cause; I think it needs to go further than that, with outreach to existing sites, as well as new services that are sure to come online. Then anyone, Google included, can pick up the structured content and do with as they please. As for Google Base, I'd be happy if it became an open means for distributing content. I send something to Google Base, and it shows up everywhere. As we see a proliferation of specialized sites, I think there will be a big market for these types of services. As an example, Whizspark already acts as a data gathering tool for events, but as a service to their clients, they could ensure that event data is distributed to all the various event services (Eventful, zvents, MySpace, Google Base, etc.).
