So, Dan, you’ll see their axes are semantics of social/information connections (which I didn’t use, I was just scattering them along the line chronologically and then just for visual spacing!). So, I probably could’ve done it linearly, but I like the visual dynamics ;). I could rearrange and possibly have one dimension be technical sophistication and the other be design elegance (e.g. the original map that led to my performance ecosystem model). Hmm….now done.

I do claim that the notion of system-generated content is mine, at least I haven’t heard anyone else make that leap (and I searched and didn’t find anyone else mentioning it, though I don’t doubt but that they have). And, yes, I do believe content creation can go on, cf my reference to Wolfram|Alpha, which I think does do that. And more can be done. Thanks!
