The DataPortability Workgroup announced this morning that representatives from both Google and Facebook are joining its ranks. The group is working on a variety of projects to foster an era of Data Portability – where users can take their data from the websites they use to reuse elsewhere and where vendors can leverage safe cross-site data exchange for a whole new level of innovation. Good bye customer lock-in, hello to new privacy challenges. If things go right, today could be a very important day in the history of the internet.—Google and Facebook Join DataPortability.org
