Maven - the name

Maven comes from the Hebrew mebin (understanding) and means enthusiast and expert; specialist. - From The Tipping Point by Malcolm Gladwell:

The one thing a Maven is not is a persuader. Alpert's motivation is to educate and to help. He is not the kind of person who wants to twist your arm. As we talked, in fact, there were several key moments when he seemed to probe me for information, to find out what I knew, so he could add it to his database. To be a Maven is to be a teacher. But it is also, even more emphatically, to be a student. Mavens are really information brokers, sharing and tracking what they know.
