We haven't changed course. As Ixiaus mentions, there are several chicken and egg problems involved around the 'semantic web'.

We're starting with specific content publishers right now that use a combination of our web-based editor (which looks like a normal editor, but allows structured content creation) and APIs to get information in to Silk. This allows them to create sites where people can play around with the structured data, create visualizations, etc.

Longer-term, we'll open up the editor to the general public. Our goal is to do to structured content what Blogger and Wordpress did to weblogs.
