Yesterday, Robert Scoble wrote a post about " Foursquare's Yelp problem ." It's an interesting read, with some good thoughts about how Foursquare can withstand feature-copying from a much larger rival. He asked for my thoughts, so I figured I'd jot some down here. Most importantly, his post got me thinking about the next phase of location, which I think we're just about to enter. First, Scoble's thought that Foursquare might be in trouble because Yelp copied its check-in badge idea seems a bit premature to me. It was a much bigger deal when they added the whole check-in concept back in January, but the fact that Foursquare has started growing faster than ever since that point shows they have an advantage over Yelp in the realm. That advantage is that they have a social graph built for location, Yelp does not (yet).
