I would definitely caution you + the author of this post to tone down the rhetoric. Heroku has earned a tremendous amount of goodwill by being... basically fucking awesome and enabling tremendous amounts of productivity without having to screw around with infinite configuration settings. Just earn your own goodwill on your own merits, not by denigrating an extremely competent "competitor"

Why would I go to the docs if you can't even describe it properly in a blog post?
