Word of mouth now has a unprecedented influence because it spreads so far and so fast.

The social-media landscape changes incredibly fast, so you have to be open-minded and nimble to keep up with it.

Maybe libertarians especially like Reddit because it is a perfect marketplace of content. Every Redditor is created equal, whether you're the highest karma Redditor or a brand-new Redditor with 10 karma points. No submissions or votes are more equal than others.

I hate phone calls, so I believe in a telephone armistice. To me, the idea of calling someone unprompted is basically saying, 'Hey, stop whatever you're doing and talk to me right now.' If you find yourself in the middle of something, getting an unprompted annoyance is incredibly frustrating.

It takes discipline not to let social media steal your time.

Unless it's really an emergency, I'm not going to bother you. And you can see people chafe at that. 'You're in the same office and instant-message each other? Why don't you just walk over?' That's the perfect example of how ingrained the status quo is. To certain people, it may seem lazy, but I would argue it's much more efficient and considerate.
