I've posted before about Ben "Ben and Jerry's" Cohen's Stamp Stampede project: Cohen is calling on enemies of corruption to stamp messages opposing the Citizens United Supreme Court decision on dollar bills. Citizens United allows for unlimited political spending, on the grounds that money is speech and corporations are people.
Cohen's running a competition to produce the best Stamp Stampede promotional photo: grand prize is a year's supply (52 pints) of Ben and Jerry's ice-cream.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
