Advogato

From Wikipedia, the free encyclopedia

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 was an early pioneer of "online diaries" which later became know as blogs. Advogato combined the most recent entries from each user's diary together into a single continuous feed called the recentlog. Advogato's recentlog directly inspired the creation of the Planet aggregator somewhat later.

[edit] 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 in a kind of peer review process 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.

The implementation of this trust metric is through an Apache module called mod virgule. mod_virgule is free software, licensed under the GPL and written in C. It is used by several websites other than Advogato.

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