The scary thing is that I started writing an article about this on the 28th, all due to a comment I was sent by an advertising agency stating that "HTTPS is only really for checkout pages". I nicely pointed out why they were wrong.

It was mentioned somewhere that if Google started giving priority to full HTTPS sites, there would be a mass scramble to convert web sites to support HTTPS. Isn't this what we want?

You can warn people all you like, but until it starts to hurt them, they won't listen.
