The vast majority of NYT comments are handled by a human moderator. This means that we have to make an editorial decision about which comment threads we will open for comments each day. Also, we adhere to a sort-of “slow moderation” theory, which posits that the best way to respect the commenting efforts of our readership is to ensure that their comments exist in an urbane, literate environment. (Definitely not an approach that is good for everyone, but it works fabulously for us, for reasons you can probably divine.) Our goal is to have every NYT comment thread offer tangible added value to each article for our readership.
