well actually I think this is the right direction for them, they lost a lot of time trying to catch up in things were they can't win, like buzz or alike. Apart from the business perspective, at least this is one thing where they can be strong, and able to match the expectation of users. Also I can't see how this is different from Amazon, business side: they got an infrastructure in order to run their other business. But there is no point in using this just internally, if this can be provided as an high quality service. Looks sane to me.
