[cloudrail]

The library sends statistical data back to CloudRail to provide statistics and notifications for required library updates. We handle this in a way that the library still works even if the CloudRail server is down or slow. The data itself flows directly between library and cloud provider. Currently we don't disable libraries because they die anyway without updates eventually.

Yes, our unified interfaces are the lowest common denominator. We provide functionality which is not available among all providers in a separate interface. The only exception are functions where the developer needs to be prepared to get an empty result. E.g. some users just don't set a profile picture on social, so you have to handle it anyways.
