IDEO design -- my favorite design and interaction house -- has posted a spiffy website about social mobiles, the cellphones Xeni posted about a couple days ago that automatically adapt themselves to social surroundings and encourage good behaviour from their owners.

(Thanks, Scott!)
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.
