Yelp has released a new feature called wordmaps: "a heatmap showing density of keywords used in Yelp reviews to reveal fascinating patterns of local discovery." They're somewhat revealing, in that they're blindingly, stereotype-confirmingly obvious. See above the wordmap for "hipster," with little pockets in Venice, Hollywood, and Fairfax, and a big red swath through the North Central eastish-side 'hoods and running to Downtown. Looks like Northeast LA, as far as it's come, still has some hipsterfication to do. Then there's "yuppie," with hotspots in Santa Monica, Venice, and Downtown (below).
