I was incredulous asked the other day why I still used Foursquare – as if it was some passing fade and I somehow missed the exit sign. In fact, I’ve remained a pretty religious user of Foursquare. According to Vizualistics I check-in about 70 times a month. While I do like seeing the service evolve, the primary reason I continue to use Foursquare is for the digital bread crumbs it allows me to leave. I believe an increasing number of services will rely on our digital footprint as I wrote about yesterday. By creating a digital record of places I’ve been I have hope I’ll be able to provide my future self with strong recommendations for any number of things I might be interested in at that point.
