Technological optimists see the internet as a prime enabler of a free market in ideas, a space in which anyone can have access to the best thinking and the best arguments. But sceptics like Cass Sunstein see the burgeoning technologies of "personalisation" – the software that enables Amazon to make recommendations specially tailored for you, or the filtering systems that enable you to construct the "Daily Me" from a set of RSS feeds from sites of which you approve – as a countervailing force heading in a different direction. They foresee an online world in which you see only what you want to see and hear only what you want to hear – in other words the fragmentation of the internet into a multitude of ideological echo-chambers, a development which would be dangerous for democracy. And if you think that's a far-fetched fear, just look at the Tea Party in the US.
