Wikitravel:Cooperating with Consumerium

From Wikitravel

Consumerium is an effort to build a purchase-recommendation system that respects the user's desires and morality. This could include buying the travel services and patronizing the establishments recommended by Wikitravel, if they in fact satisfy that traveller's personal moral buying profile. There is some potential therefore for the two projects to work together to establish some way of effectively delivering recommendations to travellers who are making choices in unfamiliar environments, and buying things they knows little about.

See this note and background on the Consumerium buying signal and healthy buying infrastructure. The more general idea of a healthy signal infrastructure might also include such things as safety warnings, "neighbourhoods not to go into", etc.
