HTTPS Everywhere! At least on co60.ca
I was able to get a certificate from StartCom that allowed me to bring my website to the 21 century. The conversion was mostly painless. My site already used relative url's in links (except some drupal content) and also give me the ambition to fix some of the nastly looking url strings. (blog.html now goes to /blog/) which looks a lot nicer.
Took about half an hour including the request, installation, and editing of some key sections of my site. If you have a personal blog and need a free ssl certificate try them out. It was reasonably painless.
