I think how you concive it now is about spam free twitter or fb and thats what everybody is talking about. I dont think thats the real story. Imagine what you could do with real time syndication infrastructure with privacy and ownership controls built in. BP monitors, blood glucose monitors, runkeeper data, music listening streams, all kinds of data streams and a robust community of app builders to build all kinds of streaming and where desired sharing. If i dont want to see your spotify listens, i can turn that off, if i dont want you to see my health info but want to share with my doc, that can happen too. Go nuts, imagine the future without having to be forced to cram it into a timeline or public feed mined for ad relevance.
