Kevin: Fourwhere promises to help journalists see what is happening at a specific location. From a business standpoint, Foursquare, Gowalla and Yelp all have built their business on checking in with mostly commercial locations. It makes sense from the standpoint of building a business for these services, but it doesn't necessarily build up a full view of what is happening on a location. If the location-based services started to provide other types of check-ins, it could provide a broader service. Conversely, journalism organisations could start providing more comprehensively geo-tagged content that could be sold to these services. Will they build the infrastructure to do it? Or will they miss another opportunity to develop a revenue stream and financially support journalism?
