[CNet] Fees come to social networking

"After months of anticipation, fees for social networking services, which let people create linked networks of personal profiles for social or professional ends, will make their debut Tuesday, when San Francisco-based Tickle starts charging for access to some profiles.

Tickle stressed that its basic social networking service, an August addition to its pre-existing matchmaking system and personality quizzes, will remain free. [T]he only thing that will require a paid subscription is the ability to contact people separated from a member by more than four links away in the social network."
