The ideal seminar, whether traditional or electronic, is a kind of long conversation, con- vened by a single person but conducted by everyone for mutual enlightenment. Its purpose is not so much to convey facts as to further under- standing of its subject, to train the minds of its participants, and so to help create a community of scholars. It is a pedagogical structure in which every member is both teacher and student
Why a listserv makes for a good seminar: it is about opinion, not facts.
