If you're looking at this and not seeing any difference between the "before" and "after" versions, it's because HTTPS Everywhere is redirecting all github urls to their SSL version, so http://jessepollak.github.io/card/ redirects to https://jessepollak.github.io/card/ then can't load any of it's javascript dependencies due to the http/https mismatch.

Bonus points for the form still working right through all of that.
