It also means that there's no executive privilege for these emails.
A reader who has a security role at a federal agency writes, "On the issue of using outside/unofficial e-mail address from official sites, the CIO at [redacted] has expressly forbade the practice for security reasons as it is all too easy to put sensitive information in an e-mail. ... Needless to say, hearing that the WH does not mandate that practice and lets [Rove] do 95% of his e-mailing from a blackberry, presumably with access to an unofficial address, is quite shocking. Still find it absolutely amazing that his clearance has not been revoked."Link (Thanks, Bill!)
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.
