Actually, I think they're facing the opposite problem. They don't need more. They're already trying to do too much. Is it a checkin service or a location review service, or is it a way to find discounts? To Foursquare's credit, they realized that checkins were just a feature and not a business by itself, so they've begun to expand. The problem is that there isn't a clear direction to where they're going. Apps that do a better job of providing reviews will likely win on that front. I see Foursquare's biggest potential in location based deals. I think that's muddled by their focus on everything else though. So I'd agree that they're in trouble. They aren't doomed, but they need to find their focus quickly or they'll be the next Gowalla.
