David Weingart has, in the course of his fannish career, filked, costumed, smoffed, pubbed a zine or two, run a soundboard and had a generally good time. He's been filk GoH and both I-Con and Apollocon and an area head at Worldcon. He speaks passable German and enough French to be dangerous. In the mundane world, he's a consultant for a software company involved in energy and commodities trading and risk management.
He spends a lot of time on airplanes.
