But folks, this is the secret hackernews site, called BookFace. This is the site that the event happened. Its also a nice site to conspire with other YC companies and YC itself as a cohesive market 'strategy'.

And according to sam altman (sama), https://twitter.com/sama/status/631874706543480832 . Fun to read through here.. "invaluable resource in helping us work through problems and tap the YC network for advice"...
Other secrets that HN/dang/pg don't want you to know is that founders can see each other with special flairs here. Of course, conspiring on BookFace also helps too.
