Frome the Economist: "Paul Saffo, a futurologist and one of the world's most enthusiastic technophiles, also looks at the downside. “Each of us can create our own personal-media walled garden that surrounds us with comforting, confirming information and utterly shuts out anything that conflicts with our world view,” he says. “This is social dynamite” and could lead to “the erosion of the intellectual commons holding society together...We risk huddling into tribes defined by shared prejudices.”"
