Vendor Relationship Management & Federated Social Web initiatives by Markus Sabadello / @versionvega are useful attempts to push the 2.0 logic further: http://bit.ly/dJjP3q. They are part of a growing movement that has a strong attention to Identity Management with ethics and personal responsibility in mind. For this purpose, they revive the decentralized / federated approaches made popular by Peer-to-Peer (P2P) before the web 2.0 rise and glory.
P2P was killed by the music & media industry for the wrong reasons: comfort and refuse to reinvent itself. Web 2.0 remained centralised, transforming consumers as authors, but not owners. This opened doors to appropriation of personal data by Corporations, which found here new avenues for making profits.
But this has not closed in no way the gap between Physical & Digital in terms of individual responsibility. Instead, this generated the privacy issue.
So, no matter what was said 10 yrs ago to kill it, see how this revival of P2P is to bring responsibility and ethics on the Digital side of our lives.
