Sorry about that. I just grabbed the link from Google Music's share button. I was on the train and was arriving at my stop.
I especially liked his comment about what the apps could do with the data once they had it. Because that's an issue today. For example, I don't mind giving an app access to my contacts so that I can easily pick from a drop down list BUT that doesn't mean they can spam all my contacts! Permissions need to get much more granular - access to contacts only to populate fields in-app as opposed to access to contacts and hope nothing nefarious happens!
