emacs command of the day

A few weeks ago, I discussed twitter.el, a nice way to use twitter from the comfort of your own emacs - and the package is gaining new features as we speek, such as 'reply'-support.

Anyway, reason to bring up twitter again is the Emacs Command of the Day-twitter feed. The idea is that every day, it provides some useful command, and it's a response to a similar feed for Vim. It's only just started, let's see where this goes.
