The idea is that if we provide social transparency and enable attribution of work to individual workers in Wikipedia, then this will eventually result in increased credibility and trust in the page content, and therefore higher levels of trust in Wikipedia.

This demo features the Wikipedia, with the text colored according to trust. Text on white background is fully-trusted text; the more orange the background, the lower the value of trust. Type a page title in the search box on the left to see the page trust-colored.
