Fans love inconsistencies. Fans claim to hate contradictions in long-running stories, but actually that stuff is catnip to them. If Londo Mollari says he has seven penises in one episode and then refers to his twelve penises in another episode, the fans will spend hours coming up with explanations for the discrepancy. Marvel Comics realized this years ago, when it started sending "no prizes" to fans who could come up with the cleverest explanations of continuity goofs. So don't worry about trying to be consistent with old stories. Just ignore them, and let the fans worry about them.Link
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.
