This graph is biased by the fact that you're searching 3 words versus one. I personally qualify searches with "rails" throughout the day, but hardly ever actually search "ruby on rails". I imagine most other rails devs do as well, so this graph is missing a substantial amount of rails traffic.

Agreed. But to be fair one would have to do the same for Node: add "node" and "nodejs". It'd be tough though, since like "rails" there are multiple contexts the words can be used. This is just one milestone; not meant as an exact comparison.
