1. From latent to explicit;Source: http://speedbird.wordpress.com/2009/03/22/the-elements-of-networked-urbanism/

4. From expiring to persistent;
5. From deferred to real-time; (Live feeds, Twitter)
6. From passive to interactive;
7. From component to resource;
8. From constant to variable;

10. From object to service;
11. From vehicle to mobility;
12. From community to social network; (Live journal to Facebook, Twitter, etc)
