Customers email me quite often showing off the sites they’ve built on top of Community Server. It’s always really fun to see what innovative new ways people are introducing social tools to an audience.

Jon, who built Vast Rank (http://www.vastrank.com/) on Community Server, provides college ranking on a number of different characteristics like social life, housing, professors, sports, and more. The reviews of course also include an overall score based ranks along with comments from students or alumni.

Google recently added Vast Rank as a featured project for extending their Maps (http://code.google.com/apis/maps/) and Search APIs (http://code.google.com/apis/ajaxsearch/).
