I like Tim Maly's short-short science fiction story, which takes the form of a Twitter bug-report:
"Yo @carzymoney," he said, "I think @timebot's got a bug in the link code. #learn2code"
It was a post by Allison. Nothing special, something like "Mmmm tasty lunch" with an image attached. The image was a broken link. No big deal. I tried to find the original tweet but there was some problem with the unique ID and you don't make it easy to page through past tweets. I'd have given up if I hadn't noticed the timestamp.
The timestamp was in the future. Two days in the future. Weird bug. But @timebot was always a side project and I was on some big deadlines.
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.
