I don’t know about you, but I can’t really remember the last time I added a bookmark to my browser (at least not on purpose, -D is right next to -F after all). So when I saw rustref.com, I knew I wanted to build something like this for the Ruby community, which is now available as rubyref.net. tl;dr RubyRef defines a list of CNAME records of the form *.rubyref.net which redirect to different Ruby related documentation sites.
