Oh wow! It took me a bit to realize this was DHH of Ruby on Rails fame (among other things). I like this message. After a career in Java, bash, Python, PHP, and a half-dozen config-definition languages, I've never found anything that evokes the joy-of-actually-writing-code like Ruby does.
Well, other than few tiny niggles like my code editor not being sure what kind of variable something is. But usually that doesn't matter.
