Ultimately though, the opinions of Hacker Newsers (a group with which I've proudly associated for ~3 years now) are only a hint at how much we're helping (or hurting) the world, and while we should always keep it in mind, we need to recognize that this is a group which is accustomed to the IRC style of social networking.
I don't blame anyone at Hacker News for thinking "we" are evil, because we do a shitty job at communicating what we're actually doing and why[1] (and we can't really communicate everything anyway). Instead, we've just gotta try to address the problems that are legitimate and be as transparent as possible.
Shortly, if you call tin foil hat theories tin foil hat theories (even with sound logic as to why they are tin foil hat theories), all you're going to do is convince the tin foil hat theorists that it's yet another elaborate step in manipulating them into believing The Corporate Directive.
And, everyone else, for what it's worth, I'd much prefer it if we could just go back to hacker news on here. I'm a C Hacker first (before being assimilated, I contributed to open source projects like Chromium and Mongrel2, because I loved the problems (coincidentally the same reason I allowed myself to become assimilated into facebook -- I work on code that's hit my millions of users billions of times a day[2])

[1] We've enabled applications to write to our network as they wish without introducing much friction or overhead (a single approval), but we've managed to communicate that in such a way that instead of leading people to believe that we've put the onus on developers (and users, as they must ultimately know which apps to trust), we've instead "put our tentacles" into yet another area and are again sharing without reason.
[2] memcache protocol stack stuff, we issue lots (and lots and lots) of requests per page load :)
