While looking around Amazon.com today, I noticed a few new things:  tagging, profile pages, and wikis.  Each product can be tagged by users to indicate what category it should be filed under or which keywords apply to it.  Each person that tags has their own profile page, which lists the products they tagged and the tags they used.  Each product can also have its own wiki, which can be used to provide more information and link to other products. 

It looks like Amazon is trying to be cool.  We'll see how long that lasts.  Many people/companies/organizations have found that user-edited and user-submitted information has a tendency to move completely away from "family-friendly" and go straight to "R-rated".  That's why a lot of big sites don't allow comments:  People say mean, offensive, and stupid things.  I think Amazon will discover this pretty shortly. #technology
