I know most of the people on here have transcended the earthbound, maudlin Certificate Authority system, but as services-adopting-SSL-news goes, I'm particular excited about Github Pages, which started quietly supporting SSL for *.github.io domains a few weeks back.
I'm excited because Github Pages is powerful, verrrrry flexible, and totally free. AFAIK, it's the only major blog/web host that gives you free SSL, backed by a high quality CDN (since everything is static files).
To promote the occasion and nudge Github to take it further, I wrote up my own experience, and a little how-to for forcing redirects via Jekyll:
Along with Cloudflare's 2014 plan to offer SSL termination for free, and their stated plan to double SSL on the Internet by end of year, the barrier to HTTPS everywhere is dropping rapidly.
