Your original comment did come across as a bit harsh but it didn't deserve anyone's downvote. I think your stance can be summed up similar to mine: Just because I haven't learned Coffeescript doesn't mean I don't plan to, or at the very least, doesn't mean I am against it. I (like you) would like to see the site's documentation in Vanilla because, after all, both Coffeescripters and Javascripters can read pure Javascript.

A side note, am I the only one that has noticed an increase in downvote-readiness here lately?
