The newest issue of Business Week includes an article called Mix, Match, and Mutate. As the author says, "hordes of volunteer
programmers are taking it upon themselves to combine and remix the data
and services of unrelated, even competing sites." In the AWS world we've already seen this happen with cool applications such as Book Burro, Zollage, Actor Tracker, and Amazon Light.
If you've written a similar application which uses an AWS service, perhaps we don't know about it. Send us some mail (email@example.com) or post a comment to the blog, and we'll take a look.
