Does the Internet need Cliff's Notes?

I have a huge problem with not having the time or patience to read all the online long-form content that I'd like to. Therefore, to solve this problem I set out to build a Cliff's Notes for the internet. 2 friends and I built a beta version of my vision and called it Gisto (lives at http://gis.to). Question is, what kind of mass appeal would a tool like this have?
