|I like watching what's going on at Google because they seem to keep inventing lots of new stuff. They were the first place I saw what we now call Ajax. (Google didn't invent Ajax, but were quick to start using it commercially.)|
For official info: The company announced Google Base on their blog, and there's an About Google Base page.
Basically, Base seems to be a place to post bits of info you don't have anyplace else to post--people without their own Web sites, wikis, blogs, etc., or at least without sites that are appropriate for the info they want to post. To keep all this info from being a complete hodgepodge, you use lots of tags on your posting to help categorize it. So this lets you post classified ads, job postings, stuff you want to sell, etc. I would look for a way to link into existing Web pages, and just categorize the link while the content remains on your own site, but I don't know if you can do that.
For external evaluation: Search Engine Watch has a thorough review ("Google Base Live, Accepting Content") as does a blog on Google ("My Experience With Google Base"). There are articles on CNet ("Google Base service goes live") and a PC World blog ("Google Base is Live").
For commentary: Infoworld talks about security ("Google Base launched with security hole") and Internet News talks about how this could become a private Google WWW ("Google Base: Toward a Walled Garden").
