Somewhere on SO, someone linked to a joke image showing the learning curve for 6 editors. The most memorable part of it (to me) was the fact that the Emacs (or vim?) chart was shown as a spiral (no offense intended to the respective users). Can someone point me in the direction of that answer?

It's the same image that Jeff and Roger linked to.
