Addons have been used in World of Warcraft for a variety of in-game purposes, such as data monitoring or making players' lives easier. What happens, however, when smart people decide to use the power of WoW's interface for a scientific and statistical purpose?
Researchers at the University of Minnesota, Carnegie Mellon University and the University of Pittsburgh, under a project by the National Science Foundation, are using an addon called WowLens to gather peer review data. The project aims to use the wealth of people, resources and data floating around Azeroth in compiling data for research projects. It personally reminds me of Folding@home, but with statistics instead of computer processor cycles for medical calculations.
