Google Base made an appearance yesterday and then quickly went dark. This new Google service is going to be offering some interesting database type services, which I am predict just from a quick look of a screen shot that was captured may compete with Craigslist and other social applications.
I could be wrong but the screen shot mentions Google Base will be a place that you can list your used car for sale. See the screen capture here and the full write up of what was on the page. [blog.outer-court.com]
