Beyond the hilarity of Batman’s hating on ‘FourWhere,’ this comic poignantly illustrates why I currently don’t use location-based services (LBS) like foursquare: I don’t want people to know where I am all the time.

I would, however, check in if my participation added real value to my life (other than virtual rewards and points I can’t really use toward anything). Using that premise as a starting point, brands — both small and large — have a real opportunity to make LBS platforms more relevant and useful than a mere location-broadcasting tool.

Do you use foursquare or other LBS platforms (Gowalla, SCVNGR, etc.)? If so, why?
