First comment on article from a Clinkle engineer: "how is this different from facebook or google plus search? i type in someone's name, i get back their full name, profile photo, phone number if it's public, etc." Fair enough, the only real personal information is your telephone number, and we don't know if they are operating like the white pages, opting out of displaying that publicly.
