For some odd reason, last weekend, this striking black and white image by photographer Terry Kane of pop singer Madonna "tour(ing) a UN millennium village in Mtanga, Malawi, in 2007" illustrated a Financial Times book review of ‘The Tyranny of Experts’ by William Easterly and ‘The Idealist’, by Nina Munk. Madonna is not mentioned in the piece and the review rumbles on. You can read it here. In any case, we were struck more by the image and posted it on our Facebook page, where we asked readers to #captionthis. We promised that we'd feature a few on the blog, so here are some of them.
