Now that the Instagram API is available with last month's public beta launch, we've started to see some fun apps built on top of it. Since Instagram's only official product is an iPhone application, that means we're seeing web clients, badge widgets and even Hot-or-Not style games. The best part is that some even cross over to multiple mobile photo APIs, increasing their reach and usefulness.
A competitor created an export tool for Flickr ex-patriots, so the photo sharing site shut down the Flickr API developer key. The Google Plus developer page makes some wonder if the "real" Google Plus API is coming soon. Also: questions about the Google Safe Browsing API, free cloud database and 15 new APIs.
