ESRI announced the winners of their 2010 Mashup Challenge. 1st place goes to Dave Bouwman and his executive compensation mashup available here.
Second place winner was a social media mapper, that presents real time results from social media websites to a map (see it live here), which seems like a great time killer to me.
Congratulations to all the winners and applicants, and many thanks to ESRI for running this challenge and allowing people to be creative with their products.
