It's weird because they've had a feature similar to this before. It was under a tab called "Nearby" or something in their left navigation. If I remember correctly it was web only but a user could access it on their phones through the mobile site. I liked it. It wasn't as one-to-one as this iteration of it though. It would only show you where someone recently checked-in. It was quite accurate though. It eventually just went away. I wonder why they got rid of that, but now are doing something like this.
