The reality is, there's still so much we haven't yet figured out. There's still so much stuff that has not been made more, frankly, efficient.

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.

Having that kind of endorsement and having Paul Graham's readership coming to your site and contributing to it and building the foundation of the community was just a really invaluable way to start Reddit.

Even if you have no interest in starting a company, having the experience of having ideas and doing them, that's muscle to exercise because that's what people are going to want to see. That's what makes you different.

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.

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.
