If I click the link from the article that leads to the webcache version, I get "yes, but embedded only".

If I click the link within that page that leads to the exact same webcache url, I get "yes, embedded and external but no ajax".

If I google the site, the preview text is the non-changing portion of the text only ("This is an experiment to...") - not even a "No".

I think Google is just trolling us.
