So I added a widget to my blog sidebar to show where FourSquare thinks I still am. Useless perhaps, but a little neat. While poking around the vast reaches of the WordPress Plugin Repository, I found the Foursquare Venue Plugin for WordPress, which looks interesting. If you have a venue that people may check into, you can extend your WordPress site to show a real-time display of who’s there and who’s the mayor. Add an incentive for whoever the current mayor happens to be (free refills, fries or a discount of some sort, whatever) and you may just encourage more FourSquare users to turn up and check in. Nice. Very Guerrilla, and social too.
