When you look at the kindle edition of books on Amazon.com, you can now see what other people have highlighted in their editions of the ebook. This means you have a fabulous way to share what you’re learning and a socially-generated way to learn from others. It’s sort of like Cliff-notes for the digital era. While I’ve struggled with becoming an online book reader, this feature shows me possibilities that truly advance publishing into a more collaborative age. Rather than just look through ratings from other readers, I’m going to scan through the points that leaped out and resonated with previous readers.
