The "Why no HTTPS?" site has been added, which itself is indeed offered without SSL.

This site purports to show the "top 100" web sites which offer themselves over plain http, without redirecting to https. The site is designed to "shame" web sites into disabling http-only access..

The site also offers interesting arguments for using https.
