Do you check-in? There’s Yelp, Foursquare, Facebook Places, Brightkite (does anyone still use it?), Google+ Locations, Gowalla, and probably a hundred other tools for checking into a location. I admit, I’ve tried them all, but only rarely check into a place any longer. I prefer to just tweet my location and a few observations (or a picture). But, I’m curious how prevalent is usage of location-services in Arizona? Does your favorite coffee shop reward you for your loyalty? Do you use location check-in apps on your phone?
