The Secret to a Successful API is Internal from #APIDays28 Dec 2012
Here is a video of one of my talks from API Days in Paris, France where I walked the internal side of APIs. This talk is derived from my post, the secret to amazons success is internal and stories I've written on Netflix's success with internal APIs.
The presentation for this talk is available in my talks section at The Secret to a Successful ApI is Internal.
You can find another video from API Days by me called Business Models For Your API as Startup from API Days, in a nearlier post.
