We all have great ideas. No one ever says, "I've got this terrible idea."

Hundreds of these companies I've seen since the beginning stages - including Dropbox and Airbnb - one of them has actually been crushed by an incumbent. The Googles, the Twitters, the Facebooks, they might be someone to acquire you, which is not necessarily a bad position to be in.

The problem is these politicians have very, very big interests in being re-elected, and the money that gets them there is provided by people who don't necessarily have the interest of the public in mind.

Being effective at social media, whether for business or personal use, means capturing people who have short attention spans. They're only a click away from a picture of a funny cat, so you have to make your thing more compelling than that cat. And that can be a high bar.

If I were a snarky Reddit user though, I would say, hypothetically, that that would just be like reading Reddit's Front Page a day later. But I'm not going to go there.

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

It's a lot easier to convince uninformed people than it is to convince politicians.
