I guess it was eventually meant to happen, Google has a database coming out soon called Google Base (which will be available at http://base.google.com ), and their intent is if it can be posted online in any fashion then use their database. And all that information will be available through searches and can be integrated with google maps. Seems more revenue for them, and also they seem to be targeting the likey of eBay and Craigslist. You can read up an interesting post at arstechnica  on the subject.
