I guess he was trying to demonstrate what you can achieve with a small number of characters. It may not be a good idea from a marketing perspective but come on... "Saw that, closed the page" is simply narrow minded.

It's not a good idea from any perspective. In my experience, the only people who cram as much logic into as few characters as they possibly can are beginner to intermediate level programmers who are in that awful phase where they think they know a lot more than they do.
