«A brief manifesto about the promise and perils of data» is what Jonathan Harris calls his work, comissioned by The New York Times. It does a good job highlighting the many ways data can and will improve our lives (and already does), while at the same time showing to opposite side of the coin. In the wake of the NSA-revelations, the dark side of data has taken center stage and some have argued that limiting our use of data should be the answer. This manifesto is a great reminder not to forget about either side.
