I’m using Foursquare more and more these days. It’s great for tracking where you’ve been through the week (or month/whatever), competing with other Foursquare users for mayorships and leader board places and also to stalk friends to see where they are and what they’re up to.

I’ve just stumbled across this web app called Where Do You Go that allows you to visualize your Foursquare check-ins in a beautiful way. Below is my London check-ins where the whiter the heat means the more times I’ve checked in to a certain place. I work in Farringdon and I’m the proud Foursquare mayor of Exmouth Market there.

Below that I’ve widened the map to show NYC check-ins from when I was visiting late last year and also wider UK check-ins. As you can see by the first image it works better when zoomed in.
