Google Experiments with browsing using several views
Take a look at :
http://www.google.com/views?q=olympics+view%3Amap&esrch=RefinementBarTopViewTabs. They have used a graphical framework that reminds me of exhibit. Interesting that they haven’t explored faceted browsing (for now, still a single search box). On the other hand, within a view you can adjust the lens (i.e: show only dates). Would that be a cool feature to add to exhibit ?
