is a scheme that allows you to embed hidden data on your website.
Goggle** will ogle it. And in searches it will use those data and present search results in the best format for the platform that the surfer is using. Not that I can see my efforts being recognised yet. eg Stroud Ceilidhs February 3rd

Not for the faint-hearted. Abandon logic, all ye who enter.

My question is:

Has anyone dabbled with this scheme? And would be willing to discuss a few points via PM?
