When the 'wisdom of crowds' turns on itself: IMDB edition

The concept of the “wisdom of crowds” is a fundamental building block of a lot of the Web 2.0 services that we see today. While not all of them are built on this core concept, major sites like Digg, Wikipedia, and Mahalo rely heavily on crowds being wise. There have been several instances of this system breaking down in the past, one notable occurrence being the infamous Digg HD-DVD revolt. On occasions like this, a mob mentality tends to take over a very vocal and active segment of a community, greatly skewing the product of their collective “wisdom.” We are seeing the latest meltdown of crowd wisdom over at IMDB, the popular movie information database as we speak.
