The post count here is significantly lower than Twitter. I shudder to think how many moderators it would take to administer Twitter. You might think that the downvote mechanism here helps somewhat, and it does, but on any large community with voting such as Reddit the ability to downvote turns the community into an echo chamber where only the largest group gets a say and any dissenting voice is vanished. I dare say we see the same thing here on HN.
