good point. ok, I should probably think carefully before inventing a security standard 'on the fly'!

I guess I was thinking along the lines that I could add my site to a Google service (just like Analytics) and when people accessed my site (https), Chrome could talk directly to Google and confirm the site authenticity, same way CA's work I guess, but run as a free service.

But as noted in another comment, anything vendor specific would probably be a bad thing for the web.
