Let's put it this way: long-ago-successful venture capitalist Jason Calacanis isn't the absolute smartest man in the business. Otherwise, he probably wouldn't obviously post anonymously to Secret after the covert app rejected a slot on his podcast.
But the thing is, Jason, pouting about it on their home turf only shows how little a podcast sit-down matters. Appearing with the Larry King of app-chatter isn't worth so much. That, and Secret has talked about the issues—they just probably don't want to talk about it with you.
