Quora is Yahoo Answers, except the majority of posters there have contracted terminal LinkedIn brain and the site has the SEO of Pinterest.

I don't think your theory about it being a CIA op is too far off - Jorban Peterman first got famous on Quora, and the power users' politics range from libertarian hustle grindet to fascist.

But, the site would be no different whether it was ran by libertarian tech bros or the US state department.
