"why do Paul Graham and YC continue investing their time and resources on this news site?"<p>A hacker wouldn't find this such a mystery. Once you build something that has users, it's hard to shut it down.<p>(I'm not denying HN has benefits for YC. But if for example there is some sort of bug that's breaking the site, loss of benefits to YC is pretty far down my list of motivations for fixing it.)
