The same can be said of many of the other remarks in the article. You could even say it is elegant that SPDY only changes things under the hood, and keeps the good parts of HTTP.

SPDY is technically very cool. It's the update of HTTP that was way overdue. I didn't even mention end-users. Not only the user-facing parts of technology are important.

I've been playing around with asynchronous notifications to the browser for more than 10 years, when I wrote a simple html/js-based continuously loading chat. I've seen it all, from polling, comet, flash-based TCP, longpoll, to finally websockets. So for me it's great to finally see server push taken seriously as part of the spec and not sewn on as a third leg :-)
