D'Aloisio is only 17-years-old. When he started Summly, he was only 15.

Summly scans the Web for news and uses an algorithm to find the type of content you want to read. Then it summarizes it for you.

Yahoo is going to shut down Summly as a stand alone app, but it says it's going to incorporate Summly technology into its own mobile apps and sites.

Clearly, Yahoo CEO Marissa Mayer wanted to hire D'Aloisio. She has been making a lot of small acquisitions like Summly. She wants to bring young, fresh, mobile-focused talent to Yahoo.

Humoursly, Aaron Levie, CEO of cloud storage company Box, notes on Twitter that D'Aloisio was born after Yahoo was founded.
