Is Hacker News comment history "private/free speech", or does YC use Hacker News comment history in judging founders, employees, business partners etc.? I'm not talking about the judgements anybody could make by googling, I'm talking about using your positions as insiders, is Hacker News a source of intel? I am not a partner or potential partner, I ask because sometimes I see people write well meaning things that make me wince for them if they are being judged.
