That's the really important thing - we use websockets pretty heavily here, and users can have bizarre issues with them. With this, it does just work. It's not the best or the shiniest, but it's the easiest and the most compatible.

Sure, but long polling and XHR streaming work for all browsers too. The article was not saying you should use Websockets, it was meant to say HTTP polling is the least efficient way possible to do this :)
