LittleSis (clever name!) bills itself as an “involuntary facebook of powerful Americans, collaboratively edited by people like you”. It’s intended to be a resource for anyone who wants to know more about politicians, CEOs, etc., especially:
…investigative journalists, social scientists, political opposition researchers, social justice activists, public interest attorneys, business intelligence types, [and] amateur dirt diggers at the fringes, posting their findings to blogs, message boards, email lists, zines, and elsewhere.
Like Facebook, the site has a particular emphasis on how all these people are connected: politically, financially, socially. The best way to see what it’s all about is to check out some profiles: Barack Obama, Michael Bloomberg, and the list of the 400 richest Americans.
