Yelp recently rolled out a 'word map' feature for major world cities that creates heat maps based on a particular term to show you where the most restaurants/bars/coffee shops/etc. associated with that term are located. The media is just running with the whole hipster thing because that's a lot more sensational than creating heat maps based on 'noodles'. Although I just discovered if you make maps based on 'sketchy', 'run-down' and 'recent shooting', my apartment seems to be at the epicenter.
Thanks to E V I L A R E S, who's so evil he intentionally mislabels restaurants on Yelp.
