Dave Winer's created a service that maps out who reads what RSS feeds -- just upload the OPML file from your RSS reader and it will add your name to the list of subscribers for all the feeds in your rota. Cool to see who's reading you, and who you're reading. Made me remember that I have a bunch of blogs in my bookmark group that I haven't entered into my RSS reader...

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.
