Looky here... When I was searching for "Santa Rosa" (No, not the City of Santa Rosa, but the upcoming Intel Centrino Platform), look what showed up in the search results:
I was able to collapse and expand the Map view of the City of Santa Rosa without refreshing (read: AJAX). It's nice to see that Google is finally doing some integration among its various services and using AJAX for it. Is this the start of Google Search 2.0?
