First off, it's a great talk about the future of publishing, ebooks, and how the Internet is democratizing and changing publishing itself.
But second, if you are a fan of presentation techniques, watch it through to the end. Craig wraps the talk by calling out about ten of the audience members by name and giving them specific challenges on what THEY should be doing. From the talk, I'm going to assume that many of them he just met in the previous day or two at the conference, and (a) he makes his point that ANYONE can be a publisher, and (b) it absolutely connects that he's taken his audience seriously, so much that he can call them out by name and state what they are working on. So powerful!
