YAHOO NEWS -- June 16 -- Konstantin Guericke says the site he co-founded, LinkedIn (6 million users since 2003), broke even last quarter. Whereas MySpace and most of the other social net sites depend on ad revenue, LinkedIn is going the subscription route. "Businesses pay us because they want to find people," he said, "and people pay us because they want to be found." If users want to contact someone from outside their original network, they must fork over some cash. $20 a month provides three contacts a month outside a person's immediate network. $200 a month allows 50 contacts a month.
