Facebook makes me hate the people I know, and Reddit makes me love the people I don't.

At the end of the day, how many ads did it take to convince you to use Facebook or Twitter? It wasn't marketing or advertising that convinced you to use these services. It was their value.

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 first step, and the thing that everyone has to do right on the Internet is make something people want.

I like sarcasm. I like snark.

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

I try to help founders as much as I can, but so many of us we won't even take meetings with people who still just have an idea, because everyone has an idea.
