amazonによるamapediaは商品に対するレビューをamazonに登録済みのユーザーであるならば誰でも編集できるwikipediaクローンで、collaborative structured taggingと呼ぶタグ付け機能が付く。

Amazon has just released a new Wikipedia clone, called Amapedia. It's described as "a community for sharing information about the products you like the most." So far Amapedia has had no promotion from Amazon, but it was discovered today by Rogers Cadenhead. Anyone with an Amazon.Com account can edit the site.
