In a post entitled How to Save the Web from Splogonoma, Doc Searls points out that many newspapers give away content when it's published (it's paid for by advertising) but put it behind "paywalls" later. That's "inside".
Outside will be the free markeplace where bad behaviors increase the value of paid content, while decreasing the availability of free content by burying it under a sea of money-making camouflage.
The "bad behaviors" that threaten Doc Searls in particular are the various forms of splogs and blog spam.
Comment: It's not clear -- at least not to me -- whether this is a serious threat at the moment. However, spammers and phishing already mean mail is almost useless for many purposes, such as letters from the bank, and Google is more or less useless for many product searches, where shopping services and "supplementary results" are making it increasingly hard to find real information.
