I accidentally in your base

I just posted an article on Police State UK called The open privacy problem. It's partly a review of the Cory Doctorow / Charles Stross talk I went to on Friday, and partly a general ramble on the conflict between the kind of data-sharing we voluntarily and happily commit on social networking sites, and the expectations of reasonable privacy that we all have - sometimes regarding the exact same data, just in a different context.
