Innovation Agents: Henrik Berggren Founder of Readmill

One major drawback to e-books is that there is no easy way to share text among friends. And there’s little incentive for Amazon or Apple to solve this problem. That makes it a great opportunity for a startup like the Berlin-based Readmill, which lets you highlight a passage, add a note, share it with friends online, and see which books are popular in your social graph. www.fastcompany.com
