this fascinating article about the internet and the recent revolution in Libya, in the Technology Review. Interesting if you're interested in modern warfare, esp. info war, from a case study perspective; perhaps not generally broadly interesting to my readership.
However, it includes this fascinating tidbit: Cell-phone penetration in the developing world reached 79 percent in 2011. Cisco estimates that by 2015, more people in sub-Saharan Africa, South and Southeast Asia, and the Middle East will have mobile Internet access than have electricity at home.
