That, right there. That's where I stopped reading. They're advocating basically building an asynchronous (in the sense of people) chat client instead of Gmail because you're supposed to "send people a letter" if you're going to begin a message with "Hello" and end with "Regards".

This article is so stupid that I don't even have the courage to dissect (or read) it further.
