A commuter in the New York area who verbally tangled with a conductor last Tuesday — and defended herself by asking “Do you know what schools I’ve been to and how well-educated I am?” — was publicly identified after a fellow rider posted a cellphone video of the encounter on YouTube. The woman, who had gone to N.Y.U., was ridiculed by a cadre of bloggers, one of whom termed it the latest episode of “Name and Shame on the Web.”
