If you're into this sort of stuff, John McWhorter describes this theory and many others in his introductory book to (mostly historical) linguistics, The Power of Babel [http://www.amazon.com/Power-Babel-Natural-History-Language/d...].

I love the Railscasts theme (http://railscasts.com/episodes/258-token-fields for example), which is what I usually use with Emacs.

For iTerm2 I copied over the colors from Visor.app's theme.. but Solarized looks really nice, so maybe I'll soon be using that instead.

I like this idea. I've often found projects that are useful or interesting, and clicking a "Follow" button doesn't seem like a fitting action. Ratings would let the community reward good developers and let the not-so-good developers know what they're doing wrong.

To give more "weight" to the system, GitHub users could have their average project ratings displayed on their profiles, and rankings / leaderboards could be generated. Users could receive badges, maybe: "Documenter of the Month — March 2011", etc.
