Mark Bernstein had some tips for web writers (I am not sure about this ww word, but "blogger" is no better. "networked writing"? not quite. "open writing"? what does that mean?!) Anyway, here is Mark's article, thanks for Jill.
Jill Walker in Norway wrote this definition on her blog.
"Weblogs are serial and cumulative, and readers tend to read small amounts at a time, returning hours, days, or weeks later to read entries written since their last visit. This serial or episodic structure is similar to that found in epistolary novels or diaries, but unlike these a weblog is open-ended, finishing only when the writer tires of writing (see narrative structure). "
继续读邓肯的《六度》。去年在桑塔费，马克介绍的是《链接》。现在接着上次（十二月十一号）的思路，似乎重要的不是Power Law，而是网路的阈值模型，因为博客网路的高联接度，更接近本质地说明信息在其中发生、传播和增殖的过程。
According to the tragedy of the commons, we can NOT be trusted to do even those things that are obviously in our collective best interests, such as taxation. The utopian balance of public and private interests in this situation is inherently unstable. This dilemma "expresses the inescapable conundrum of individuals who have their own interests at heart and who can control only their own decisions, but who have to live with the consequences of everyone else's decisions as well." ("Six Degrees" by Duncan J. Watts, 2003, p 204 - 219)
But not every dilemma has to end in tears. So Duncan's question is "what are the origins and preconditions of cooperation?"
This leads to the problem of information cascade. During such an event, individuals in a population essentially stop behaving like individuals and start to act more like a coherent mass. It can happen slowly or rapidly. However, what's in common for all information cascades is that once one commences, it becomes self-perpetuating; that is, it picks up new adherents largely on the strength of having attracted previous ones. Hence an initial shock can propagate throughout a very large system, even when the shock itself is small.
And here is its connection to news: " because they (information cascades) are often of a spectacular or consequential nature, cascades of one sort or another tend to make newsworthy events."
