While Coco Khan (27 March) rightly highlights how “weird” LinkedIn is (who doesn’t loathe the bragging and happy clapping?), she shouldn’t damn the entire platform. It enables millions of small enterprises such as mine to professionally connect with peers and potential clients. And yes, this means establishing brand and credibility. If she craves “a bit of real and refreshing honesty”, she may connect with me and discover how many highly talented and ethical peacebuilders, humanitarians and philanthropists are actively committed to bringing justice and peace to our world.
