We also see unique opportunity in Friendlee’s synthesis of the
‘weighted’ social network of users with a recommendation
system. The intimate network of contacts is both a source of
recommendations for businesses (and people), and a measure for
the potential relevance or strength of the recommendation, using
e.g. the network distance between the recommender and the
recipient of the recommendation. While not all frequent
interactions with a business are necessarily positive, it at least
indicates that the contact has had significant experience with the
business and can provide insights into the quality of its service.
