One of the important factors in their model is the *cost* of communication: how hard it is to exchange information. It’s often suggested that by lowering the cost of communication, electronic networking will make it easier for everyone to access information and so will flatten the social hierarchy. The researchers find that, if there is an initial inequality in how information is distributed, lowering communication costs counter-intuitively sustains this steep hierarchy and promotes inequality. There’s less incentive to spread information around: you can just keep on looking until you find it. If we want to avoid this effect of cheaper communication, they say, then we’ll need ways of compensating for it – for example, by greater social investment in education to disseminate knowledge. The web won’t do it for us." I don't get this last bit - "There’s less incentive to spread information around: you can just keep on looking until you find it." Does the author mean that because information is more abundant that rather than actively sharing information we expect other people to able to find it for themselves?? Kevin
