Interesting post over at Mashable today about the failure of many social network sites to take down personal images even after the user has explicitly “deleted” them. The issue of data take-down is one we’ve started discussing in the W3C Social Web Incubator Group. The example of deleting images you’ve placed online is a simple one, but what about all the other digital traces we leave on the Web? In a world where more and more of our identity is expressed online, should data take-down be a universal human right? We’re collecting user stories that illustrate concepts like this in order to provoke some thought, both about what the future of a more social Web should look like and what technical underpinnings need to be in place to make this happen.
