Urban transitions

Maybe its just because I'm currently reading Caryatids (hardcover) and Down and Out in the Magic Kingdom (Stanza, if you have an iPhone, get it) simultaneously, the near future has been of interest. That in mind, see Adam Greenfield's blog, where he logs fourteen transitions to a networked urbanism, such as "from expiring to persistent," and "from ownership to use." Add Clay Shirky to the mix and you've got some observant and supple thinking about networked societies and ambient, intelligent landscapes.
