Great article; I agree with him wholeheartedly. To those who think that faucets are supposed to be like double-doors, I understand, but usability is not always about idealism or philosophy. Sometimes it's about consistency. If most faucets operate one way, wrongly or rightly, then doing it differently forces the users to do it wrong the first time (or first few times) he/she uses the product. The book that comes to mind is "Don't make me think" by Steve Krug. He did not advocate perpetuating "wrong" convention, but the point is still valid: don't waste the user's time by designing something to behave differently than "expected".
