Essembly is a non-partisan political social networking website that allows its users to connect with one another based on political opinions, participate in unmoderated discussion, and organize for political action. It was founded in 2005 by Joe Green, a Harvard graduate and college roommate of Mark Zuckerberg, the founder of the collegiate social-networking site Facebook. Essembly differentiates itself from other social-networking sites by actively promoting intelligent discussion and debate while remaining (as the site's "About Us" page claims) "fiercely non-partisan."
