On mobile, what are the core apps? It's basically messaging, mapping and review data.

Starting a company, your success is going to be very dependent on how you adapt. You're going to make decisions, you're going to make bets; most of them are going to turn out to be wrong.

The entrepreneurs that really make it are the ones that start with an idea but are ready to change it at a moment's notice.

You have to be very nimble and very open minded. Your success is going to be very dependent on how your adapt.

Everyone is panicked about the transition to mobile. I don't lose any sleep whatsoever.
