Cool ‘Identity Search’ Tools for Social Web (makeuseof.com)

“(1) Yoname: Extremely simple to use and rather fast profile search tool. Lets you search by (1) email ID, (3) username or (3) by First, Last or Full name on all major Social Networking websites except for Facebook (MySpace, LinkedIn, Friendster, Windows Live Spaces, Digg, Match, Xanga, YouTube ). What’s cool about it is, how it conveniently groups search results by network in expandable menus.”
