I've had first-hand experience of Future A. I started an ebook publishing company in 1991, two years after the Web was invented and had ebooks in an ebook Internet bookstore in 1995, the year Amazon was founded, although it wasn't Amazon.

So I was primed to think about the future of ebooks and digital publishing. In August 2009 I wrote a post on the blog I was writing at the time (the cloud and me) called 3D knowledge networks which was about how I thought knowledge could be/would be presented in the future. In November of that year I came across DebateGraph, many specifics of which matched the items I had discussed in my post.
