I couldn't resist sharing this... MIT has developed, Immersion, a platform that allows users to easily play NSA and "spy" (really just visualize) their email/social media behavior.
Try-out-out and see for yourself... as we continue to develop and think about both data display, utility and personal identity in the context of the future of learning, it is interesting to explore this new way to visualize your own metadata.
Thoughts?! Useful? Useless? Nice to look-at?
