The actor of his own ideal
Using economic models US researchers predict new tactics to exploit the personal information that online social-networking sites provide.
One effective strategy could see free or cut-price products offered to the most influential online individuals to kickstart new fads, says Jason Hartline, at Northwestern University, Illinois, US.
Some very targeted advertising schemes using social networks exist, for example Facebook’s Beacon system, which can tell your friends when you buy products on other websites. But Hartline says they will get smarter.
