His self-deprecating manner makes him come across as an "accidental editor" but also suggests some of the stories for which his newspaper has been praised were also accidental. The notion that his man in Hong Kong should not have heard of Snowden before the day he landed is ludicrous. If true, what had he been doing before? If false, it is unnecessarily coy and false.

As for the description of how "most people" thought of the Huffington Post speaks volumes of the fog of smugness with which journalists treated the rise of the Internet.
