Here's some positive fallout from O'Reilly's Emerging Tech Conference: Amazon is now offering a Web services interface to their data. Jeff Bezos attended the conference and was apparently listening quite closely to all the hype about Web services (including Meg's talk on Web Services for the Real World). Like Google's API, it'll be interesting to see what people do with this.
(Amazon was offering some limited Web services before, but these are implemented in a couple of different ways with more features and is open to anyone who wants to apply for a developer's token.)
