The New York Times boasts the highest number of Twitter followers among US newspapers (more than 2.5 million — which is more than five times the number for the WSJ), but the paper is constantly refining its social media strategy.

And to everyone's surprise, these humans are posing questions, retweeting content, and curating more active online conversations. You know, social media stuff.
