How many websites use SSL
I'm writing an article on privacy on the internet, and I'm interested in getting a statistics on the usage of ssl. 

Do any of you know any ressources on this? 

I can do something like this http://www.google.com/trends/?q=http,+https&ctab=0&geo=all&date=2011&sort=0 but this will only show the interest, maybe I could argument that this would work as a proxy?
