A few data points:
“By definition, the Windows data represents behavior under the terms and conditions of the Windows/Office/DRM/PlaysForSure contract with the user — managed via IT, structured around the corporate hierarchical notions of enterprise ownership of user data and behavior, and so on. And in turn, the same can be said of the Google/Skype/Yahoo/Salesforce contract — different in that users can navigate across corporate domains but remain subtly constrained by, as Doc suggests, the tyranny of inference derived but not related from the user’s behavior. Both clouds are captured, prisoners of war in the battle for access to the intentions of the user/creator of these signals.”
“It’s a market opportunity to equip the demand side with better tools for relating to the supply side. That’s what Vendor Relationship Management (VRM) is about. When we have that, the supply side will start rebuilding their CRMs as systems that actually relate to us, rather than try to corrall and milk us like cattle.”
Dave Winer thinks it’s about getting critical mass:
“If I had a place where I kept my movie ratings and gave [Netflix and Yahoo] a pointer to it, they could read it and I would control the data. It would be very easy to set up, the technology is no trick at all. The hard part is getting enough users to do it this way to gain critical mass.”
[ed. - I'm a technologist, and I'm also a pragmatist. There are some portions of this that will be solved via technical means, naturally. But, in my gut, I still feel that a big portion of this will be solved the way that business has been done for the past few millenia, by way of actual people connecting with each other and building trusted relationships.]
