The only thing I notice is that people like and use groupon. Just this past Wednesday there was a status update in my news feed: "I ♥ Groupons!" from a recent college graduate who teaches English as a second language (ie not a hacker or startup nerd). That's one obvious difference between Iridium and Amazon. 10 years ago, when Amazon was still losing money, I had already made purchases from them. It was the first place I checked if I wanted to buy books online. I had never heard of Iridium. I don't think groupon will be as successful as Amazon, but having real fans among consumers is a big deal.
