I am pretty sure that at least some SpaceX engineers are reading HackerNews.

But I don't think I ever seen any insiders comments here, even anonymously.

Assumption not required. US ITAR regulations mean you're federally "encouraged" to be tight lipped. Add in the fact SpaceX is ahead of pretty much everyone else...
