As a 17 year old I think this is awesome and stupid (at the same time). It's pretty eye opening that if a 17 year old can make an app and get bought for a lot of money, it's possible for anyone to.
As awesome as it is for the guy, this doesn't change the fact that a Summly got paid so much for a 2 employees and a founder. I mean the app hardly had traction and $30 million can you get you a nice army of talented mobile developers with signing bonus'. $30M really isn't justified in this case.
Congrats to the summly team, but it's also really sad how desperate and pathetic Yahoo is.
