The orange box in the middle and brown ovals at the bottom cover some the themes I'll be writing about in the next chapter of Josh's and my book. The chapter is tentatively titled 'Building a Web 2.0 Business' and will explore the principles of Web 2.0 business. e.g. "Services, not packaged app".
I've just finished my first chapter, which was a general introduction to the 'Web as Platform' concept. So this will be an interesting follow-on from that.
Alex Barnett has done a nice "Microsoft mash-up", inserting links.
