I don't feel like a different person. My motivation has always been to do technology apps and companies, not making money. Just because the money's come, nothing's changed.

I thought of the idea of Summly in March or April 2011. I was 15 years old and I was revising for some kind of history exam. The problem was I was trying to find information that was useful to me. When you type into Google an esoteric term, you get quite a lot of stuff that's not relevant.

Be fearless and don't be afraid of failure. There is no better way to learn than through trial-and-error.

It's the scale that Yahoo brings - and that user base - that I really want to build products for.

One thing I'd like to do is angel investing in small companies. That's what's exciting, and if you are lucky to have a bit of money, you can take those risks.

There is a generation of skimmers. It's not that they don't want to read in-depth content, but they want to evaluate what the content is before they commit time. Especially on a mobile phone - you don't have the phone, or cellular data, or screen size to be reading full-length content.

The App Store has democratized the creation of content. As a 12-year-old kid, I was able to put my application on the store. No one knows whos behind the screen so you cant tell Im a 12-year-old.
