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.

On U.S. election day last year, November 4th, I co-organized with Katrin Verclas of MobileActive a Barcamp style event we called “Mobile Tech 4 Social Change” focusing on the increasing role mobile technology is having in social activism, grass-roots organization, social development, and in the developing world. It’s possible we started a movement because MobileActive has gone on to run two more camps since then, in New York and Washington DC. Now Mobile Tech 4 Social Change is coming to London. I’ll be hosting this event on May 23rd in at Vodafone’s offices in London. For all the details and to register, go to MobileActive.org’s page on the event. If you’re interesting in helping to build a bridge between the mobile industry and the social activism / social development space then I encourage you to attend!
