Fast Company – What Is a Curator in Chief?:

"Machines may evolve, but they'll never have a human sense of relevance. "As curator, I need "gut instinct". As I'm scanning the web (with our tools), I sometimes find sources or articles that I think are valuable--even though they might not be a perfect match to our customers' specifications. In essence, the curator curates not only the content, but also the technology so that the results are always improving while the algorithmic rules are adapting."
