…this is, without a doubt, a game changer

@jack, I agree. I love this iphone app. I mean, i absolutely love this app. If you havent downloaded this app yet, you are missing out, big time. Retail merchants, pay attention. This service will change the way you interact with consumers and build brand loyalty. My work on the twttr 101 sparked my obsession to help local businesses offer an innovative, unique customer service value proposition. 4sq is that channel. It’s live, and it’s real time. This is going to be big. more later.
