As a founder, is it wise to admit that you're just not that into how your company is run? If you're Tumblr founder David Karp, that might just be another item on a long list of things you don't care about.

In a New York magazine interview, Karp impressed his interviewer, Molly Young, with the number of topics he found dull. She wrote:

Among the topics that bore him are cars ("I don’t like cars anymore"); Internet comments ("Gross"); his company’s colossally expensive infrastructure ("I have a very rudimentary understanding of how Tumblr actually works these days"); and management ("I’m not super-passionate about how we run the company").

But these aren't the first things that Karp is admittedly cool on. In fact, the 27-year-old CEO, who in June sold Tumblr to Yahoo for $1.1 billion, has a long-standing pattern of interview honesty regarding what he doesn't like.  

"I'm very antischedule," he told Inc. "Except for board meetings, I don't really schedule things or keep a calendar. I think appointments are caustic to creativity."

"I don't know how you could live in Palo Alto. It's just boring," he said to the Wall Street Journal.

"I don't like screens very much," he told T Magazine in a story about the design of his Brooklyn loft. "'Big bright monitors drive me nuts'; screens in the bedroom are 'gross.'"

So what is Karp into? In addition to coding and simple design aesthetics, Karp is currently obsessed with drones. "I fly my drones all over Brooklyn," he told Young. "These things are amazing. These things are not regulated. I keep destroying them. I’ve had five of them.”
