Google now has over 400 cities included in its transit service. That means each of those organization provides a feed so that the search giant can give accurate routing, schedules and fares. So, why isn't it easier for the average developer to access this data?
Foursquare, the leading location-based social tool, announced a major new initiative last week to expand its location database to include cross-references to corresponding venue listings from other services. As characterized in the announcement post on the company blog, the goal is to make Foursquare the missing "Rosetta Stone for location, allowing you to link information about a real-world place from one database to any other." Now it's not just about using Foursquare, but connecting it to other services.
