Here are a couple other interesting bits about the A9 Yellow Pages:
While my previous post on the topic was more about the UI of the feature, I just noticed another interesting part of the page:

Clicking that button takes you to a fairly comprehensive set of web forms which allow the business owner or any random websurfer to contribute metadata about that business—things like phone numbers, email, website, hours of operation, and credit cards accepted. This, along with the fact that all of Amazon’s existing commenting and recommendation features are available for the businesses, made me realize that what they’re really doing here is planting the seeds for ownership of the real-world metadata game as thoroughly as they’ve captured the product-metadata space.
What’s the typical place to link to if you’re talking about a book or DVD online? Amazon. (I’ve even got a plugin on my WordPress installation that automates these sorts of links.) Amazon really realizes that they’re in the cataloging business as much as the product-shipping business—I don’t have a reference handy, but I remember Bezos saying that they could always make a business licensing their catalog (with all the rich comments, ratings, and other user-contributed metadata) if the “selling things” bit didn’t work out. Now they’re poised to become a definitive resource about local businesses (and other physical entities).
As good a job as I’m sure they’ll do with it, the fact remains that according to their license, Amazon’s dataset (including user contributions) is proprietary. (That could be one reason why they decided to run their own GPS photo trucks rather than employing pre-existing road-photo data sets.) They alone ultimately control what can be done with it. Wouldn’t it be better if we could find a way to collaboratively build similar systems without throwing our work over a proprietary wall in the process?
