Doc Searls Goes for a Ramble on the Commons

Doc Searls has a long - very long - ramble around the idea of the commons, especially the Internet commons. I didn't quite emerge with any clear idea of what he was getting at - other than the thought expressed in the first sentence:

Is it possible that, for all our talk about The Commons, the Net doesn't have one yet? Or at least not a complete one?

I'd say that the Internet has lots of them - open source, open access, open genomics etc. - but I think he's using commons in a different way, one that is much more rooted in the original idea, as in Clapham Common. I also got the impression, that this was very much a To Be Continued.... so I look forward to more rambles in the future.
