Are you using a location based service? What about the iPad? Or how about Posterous ? All of these things have at one time been labeled overrated . For example, I think foursquare is a complete waste of time. Why the heck would I want to tell the world where I am! I mean that's really nobody's business! It's not like Twitter where I actually have meaningful dialogue . I find value in Twitter for numerous reasons. I can't imagine finding that same value with foursquare.
