Instagram's Real-Time API
1) Users of the developer’s application: every time a user of an Instagram-linked application posts a photo, the developer’s application will receive a notification. Developers like Foodspotting and sites like Dropbox now both utilize this new functionality.
2) Tags: An application can track a given tag and receive updates every time a new photo is posted with a given tag.
3) Locations: Every time a new photo is geo-tagged with a specific location, the developer will receive a notification.
4) Geographies: Sometimes individual locations are too specific. For these cases, we suggest subscribing to Geographies. Geographies consist of a latitude and longitude and a radius. This allows developers to subscribe to a given area like Austin or a specific city block of Manhattan.
Might be a good opportunity to play around with a blazing hot iPhone app.
