It turns out Yelp has done just that, producing a heat map of my home city of all the reviews that mention posh. It looks pretty much as I’d imagine.
The same applies for the term hipster. I’d immediately associate the area around Hoxton and Old Street (AKA Silicon Roundabout) with all things hipsterish. As it turns out, so do Yelp’s reviewers.
All of which is oddly comforting. Maybe my mental map of a city isn’t so personal and subjective after all.
A tip of the hat is due to Chris Osborne for pointing out these mapping gems.
