Turgeon states his thesis "has a duel hypothesis. The first hypothesis revolves around pizza-style preference, identity, common regional styles and the idea of home. The second hypothesis deals with (VGI) Volunteered Geographic Information and the uses of social media and crowd-sourced data to acquire information for web-based mapping."
The VGI information is displayed on map. Turgeon's website is just getting started but there is not a lot up right now, however, but as time goes on he is sure to add more.
