If you know what you want, you use Google. But if you don't know what you want, and you want to be surprised and find something you didn't expect, we want you come to StumbleUpon. Really, that idea of being a discovery engine versus a search engine.

The way the Facebook network is set up, it's not as suitable for content discovery. Twitter is better, but there are too many over-sharers.

A lot of productivity is capturing ideas. I use a wiki - it's more valuable than e-mail for running a company - and I have a page for every person with whom I interact frequently.

Social media has come a long way. With the good has come some bad, and you always have a lot of people hiding behind their computers and being very critical of what you do on and off the field, of what you tweet, of what you say, of everything you do.

For us, it's about having the game react to the player as much as possible. There's ways you can do that with technology, graphics, AI - we're doing some VR stuff right now - and so it's what we think is great about not just our games, but what's great about video games - how are they better than any other form of entertainment?

The Internet has enriched my own life immeasurably.
