Hashtags continue to be a hot topic in the office, particularly after the most recent #growthackingexperiment.

Now the lovely people of #tagsandthecity have provided a map of the London Underground trains accompanied with the most popular hashtag per station.

We can pretty confidently vouch for that the Book of Mormon is the best part of the Piccadilly Circus area, visiting Covent Garden without going to Shake Shack would in a word be a disappointment and is there anything in Knightsbridge but Harrods?

So as far as we know, this seems to be pretty accurate. What a neat way to see what's the most popular thing per locale.

The same is also available for Berlin, New York, San Francisco Bay Area, and Paris.
