One look at this map (From the Public Internet Project via Werblog) showing Manhattan’s wi-fi nodes should be enough to prove that the biggest digital divide of all is the one that runs roughly North-South down the middle of the Atlantic Ocean. What would a similar map of London, Paris or Berlin look like? Sparse, I’ll bet. The distribution of nodes within Manhattan also speaks volumes of the divide at ground level, though. If I remember rightly, the big, empty zone at top right is dominated by social housing likely to be light on Wi-Fi. The graphic recalls Booth’s extraordinary 1889 map of London, visualising Victorian urban poverty for the first time in startling, block-by-block detail. (got this wrong yesterday and credited the maps to Mayhew who wrote about the London poor. Luckily nobody visits this weblog so I think I got away with it).
