Take a look at that picture (h/t Bill Easterly & @portlandcomms). The highest number of tweets over a three-month period come from South Africa, Kenya, Nigeria, and Egypt. These countries also show the highest number of tweets per citizen. Each is a former British colony which continues to have strong ties to the wider English speaking world. (Click on the chart to enlarge.)Former French colonies are far behind in tweets per person and twitter usage in general, with the exception of Rwanda, which is increasingly turning its back of Franco-Belgian Africa and integrating with the Anglophone world.Sixty years after most African countries became independent, the legacies of two very different colonial imprints remain strong. Even in cyberspace, French (and Belgian) colonialism looks like a particularly grim curse.
