This is a cool service! applying one of the latest technologies to drive selling books, something that is getting harder when time progresses due to people reading less. They say: Reading books makes people more intelligent, over watching television or video on youtube or whatever online video service. Someone asked the other day: we are getting dumber by the day then? It may not go that quickly, but yes, the chance is that we collectively are getting dumber by reading less. Love this hunt/service!
