Professor CK Prahalad has challenged corporations to focus on serving the bottom of the pyramid. His book is a very inspiring read.
I have often wondered how to link his ideas to the broader shift to a network era that allows knowledge-workers to participate in the global development. What we need are applications that specifically focus on the value that can be delivered to those that can be characterized as being at the bottom of the pyramid. Here's a video of an experiment underway in rural parts of South India. This is impressive. We need to scale up such initiatives. We need to learn from these initiatives and adapt the applications so that they continue to deliver superior value. We cannot afford to have the network era worsen the digital divide. Network era has the opportunity to close the divide between the rich and the poor and this should be pursued.
