More interesting is that everyone in publishing entrusts their rankings and status to a single provider. That's the story no one likes thinking about in publishing.Indeed it isn't just publishing as Barron's reports Amazon is responsible for about a third of all online eCommerce in the US. This is why Amazon needs to think carefully about how to react to this sort of thing in the future. Amazon currently is pretty cavalier about these sorts of issues and believes that they will get forgotten about. That may be true of each specific case but each one of these hits erodes the Amazon's reputation with its customers. After enough erosion we could easily see some other competitor (or competitors) arise to take market share away just as fast as Amazon gained it in the first place. I don't think there's any point in expecting the publishers to do this themselves - going on the ebook thing the one thing you can be sure of is that the publishers have innovative spirit as a sedimentary rock - but I expect someone else will because the more of these things we see the more vulnerable Amazon becomes to more agile competition with less of a hacked together website.
