I’ve seen a lot of people suggest with Google Base they’re competing with Craig’s List and eBay, but I see it much more as a play against Wikipedia. When I chatted with Jimmy Wales he said one of their biggest problems was for things that are relatively structured like the wiki dictionary or quotes having hte data in a totally unstructured wiki format makes it hard to work with. He suggested they would go the direction of mediawiki templates and microformats, which is great to hear. Google has come at it from the other direction, giving you a free-form DB to pour your heart into. I guess the question is, will people become as passionate about distribution (what Google promises) rather than working for the greater good of humanity through the Wikipedia.
