Chris Anderson has made a recent interview he gave available on his blog. At around eight and a half minutes in he discusses the trade-off between access to services and privacy online. I particularly liked his characterisation of the web as the best machine ever created for tracking patterns of behaviour. In summary, he suggests that a loss of privacy to whatever extent seems to be the price we pay for free online services and ubiquitous access to information. Given the massive and unstoppable growth in internet use, that seems to be a price we are prepared to pay (for now?).
