The app ecosystem, powered by widespread mobile broadband, is an undeniable success story. Case in point, courtesy of Kara Swisher from All Things Digital:

Earlier today, Yahoo said it had acquired the trendy and decidedly stylish news reading app Summly, along with its telegenic and very young entrepreneur Nick D’Aloisio.

Yahoo said it plans to close down the actual app and use the algorithmic summation technology that the 17-year-old D’Aloisio built with a small team of five, along with a major assist from Silicon Valley research institute SRI International, throughout its products.

You read that right. A 17-year-old whiz kid and a small team have just sold an app to one of the biggest online players. The kicker? Yahoo! paid $30 million for the app. Wow.
