Wiki Surveys: Open and Quantifiable Social Data Collection
Fig 1
Schematic of rank order plot of contributions to successful online information aggregation projects.
These systems can handle both heavy contributors (“the fat head”), shown on the left side of the plot, and light contributors (“the long tail”), shows on the right side of the plot. Traditional survey methods utilize information from neither the “fat head” nor the “long tail” and thus leave huge amounts of information uncollected.
