I agree. I went from the semi-general statements found in this post (robots.thoughtbot.com/post/10125070413/unobtrusive-ruby) and cast them deeply into Ruby examples, but I think that you could go in the other direction with this and find that these concepts are already expressed by some existing general OOD principles. However, that direction seems harder to trace than just coming up with a code example for each point :)
