It takes balls to say anything bad about Javascript, CSS and "web apps", especially to an audience full of web designers. If I could upvote you I would. But my browser does not support Javascript and I don't think upvoting is REST-friendly.
Please tell me that was sarcasm, man. It's one thing to support someone having the balls to come out and courageously support an unpopular but just position. Unfortunately his comment was just flame bait and not even close to courageous.
