Fantastic new podcast from Radar on reputation and ranking models, including Hilary Mason of bit.ly and Sean Taylor at NYU. The clear outcome is long-term social rankings are heavily and disproportionately affected by positive early votes. This reinforces to me that the social structure of communication has a large impact on social norms.
Podcast: ratings, rankings, and the advantage of being born lucky.
Thanks to ghelleks for the pointer. He knows I <3 this stuff.
