Henry Blodget doesn't exactly pile on with the Groupon (GRPN -5.4%)-bashers as much as he simplifies the debate. Though the comparisons to Amazon (AMZN -0.5%) are valid, he argues, the oft-quoted problem for the company isn't that Andrew Mason won't match up the Jeff Bezos at the helm. Instead, the issue works out to simple math: Amazon went public at a $500M valuation, vastly lower the lofty $20B  price tag on Groupon that could limit spectacular upside potential.
