Part two of The Webby Debates, hosted on and moderated by that site’s Laurie Segall, featured TechCrunch columnist Paul Carr — who quit Facebook and Twitter in August — discussing the future of social media with Wine Library TV host Gary Vaynerchuk.

Carr: But people trust you. People come to it with an idea of what Gary Vaynerchuk is.

Vaynerchuk: They trust me because I … and by the way …

Carr: If you become known as the guy who was accused of a crime on Twitter, and that’s all people know of you, good luck rebutting it, because you’re that guy.
