What's a Friend Worth? - Knowing Your Social Capital
summary
IBM Research mines 20 million emails and IMs from 10,000+ distributed social sensors across 76 countries to build a prototype (Small Blue) that maps expertise, trust paths and social proximity inside a 400,000-person enterprise. Findings: a direct contact in your network equals $948 per year, a strong tie to a manager adds $500 per month, diverse networks boost value more than cohesive ones, and email-mining required global privacy and legal reviews before production.
