You make a great point. The profit margin on the product may be very low, yet the developing world (which this effort seems to be targeting primarily) is a huge market, and the investment will pay off greatly. Plus, the product will be for a good cause. Win-win situation. Secondly, Google is harvesting the wisdom of the crowds with this call. No doubt there will be several great gems from the fringes. I am looking forward to see the top 100 list. I am also confused a little. Google states that the Google employees will go over all the submissions and choose the top 100 list. Wouldn't that be incredibly tedious? I wonder what tools they will use to speed things up. I think this would make a great job to submit to the Mechanical Turk.
