In 2005, 43 Things won the Webby Award for the best social networking service.

43 Things was launched on January 1, 2005, by the Robot Co-op, a small company based in Seattle founded by blogger and developer Buster Benson (né Erik Benson), Maktub keyboardist Daniel Spils, and former Amazon.com and Microsoft executive Josh Petersen.
