The Googles, Amazons and Facebooks of this world, which are the only outfits (outside of the US National Security Agency) with the computational resources to mine, analyse and process the data torrents unleashed by us as we go about our networked lives. The companies don't talk about it this way, of course. Instead they have soothing patter about how their analytical capabilities enable them to serve you better: how the ability to analyse the web searches conducted by you and your friends enables them to provide better search results, for example; or how analysis of your online behaviour enables Amazon to suggest products that you might like; and so on.

All true, of course, but skilfully avoiding the awkward fact that you are the resource that is being mined and that the playing field that is cyberspace is tilted in favour of the corporations who have come to dominate it.
