Mobile ad network Millennial Media, believed to be weighing an IPO, claims the number of ad impressions it's delivering to Kindle Fire users has been growing at a 19% daily pace, with the monthly total now in the "hundreds of millions." Goldman, for its part, thinks Amazon (AMZN) could ship 6M Kindle Fire units by year's end, and 15.5M-20.5M next year.
