The article by Doc Searls and David Weinberger (see this earlier post), 'What the Internet is and how to stop mistaking it for something else', comes with a sidebar of 'essential links'. A key text is David Isenberg's 'Rise of the Stupid Internet', and this can now be found at two sites. There is a revised version of this essay, too, 'The Dawn of the Stupid Network'. Isenberg's own site provides links to other important articles. Now, Ken Camp, in his blog Digital Common Sense, takes issue with Searls and Weinberger.
Weinberger's Small Pieces Loosely Joined: a Unified Theory of the Web is perhaps something we should buy and have a look at.
