How is GTFs "..not particularly useful for developers"? I played around with it a little and found it to be perfectly usable/useful comma-separated values.
+! GTFS is super awesome and most apps I know rely on it. Its consistent format that is adopted by transit systems across the globe. couldnt get more developer friendly than that. If you developed with this RESTful API, it would be hard to adapt your app to use the feed for a different city.
