Joho the Blog » [2b2k] My world leader can beat up your world leader
"On the other hand, information is now passed around if it is made interesting, sometimes in jokey, demeaning ways, like an article that steers us toward beefcake (although the president of Ireland does make it up quite high in the Reddit thread). The information that gets propagated through this system is thus spotty and incomplete. It only becomes an occasion for serendipity if it is interesting, not simply because it’s worthwhile. But even jokey, demeaning posts can and should have links for those whose interest is piqued."

Tracing information flow on a global scale using Internet chain-letter data — PNAS
Although information, news, and opinions continuously circulate in the worldwide social network, the actual mechanics of how any single piece of information spreads on a global scale have been a mystery. Here, we trace such information-spreading processes at a person-by-person level using methods to reconstruct the propagation of massively circulated Internet chain letters. We find that rather than fanning out widely, reaching many people in very few steps according to “small-world” principles, the progress of these chain letters proceeds in a narrow but very deep tree-like pattern, continuing for several hundred steps. This suggests a new and more complex picture for the spread of information through a social network. We describe a probabilistic model based on network clustering and asynchronous response times that produces trees with this characteristic structure on social-network data.

Chain letters reveal surprising circulation patterns
Contrary to predictions that large-scale information spreads exponentially, like an explosive epidemic, the researchers found that the letter did not reach a large number of individuals in a few steps. Rather, it took hundreds of steps of people forwarding the e-mail on to reach the 20,000 who signed the found copies.
