Perhaps the other useful part of the Amazon analogy is that I believe that GroupOn will slowly be eaten alive by competitors unless they bring some real business and/or tech innovation. Last I saw, LivingSocial's trajectory was steeper than GroupOns. I think we can expect LivingSocial to go public soon so they can add some cash to their war chest.
