Advogato is an online community site dedicated to free software development, created by Raph Levien. It describes itself as "the free software developer's advocate."

Advogato's trust metric

The motivating idea for Advogato was to try out in practice Levien's ideas about attack resistant trust metrics, having users certify each other and use this information to avoid the abuses that plague open community sites. Levien observed that his notion of attack resistant trust metric was fundamentally very similar to the PageRank algorithm used by Google to rate article interest.

There is a wiki, called AdvoWiki that applies Levien's theory to sort wiki pages by interest level.
