I'm going to elide pointing to examples because several of those companies would institutionally prefer that there exist no backchannels into their org charts and it is definitely to the interest of HNers that HN continues to be an effective escalation mechanism into their org charts.<p>It is probably important to your understanding of Big Companies (TM) that a big company is referred to as a single entity for purposes of corporate personhood and shorthand, but they rarely act as a single body, but rather as a collection of people and sub-organizations who are colliding together in Brownian motion.
