We live in a world where we're all accumulating more online data about where we're going, what we're doing and how we're reacting to the world around us. But what are some of the implications of that? We explore our changing relationship to data and our virtual selves. We also meet the creator of a project called We Feel Fine, which provides a glimpse into the soul of the Internet. And we also talk to one of the founders of the Museum of Endangered Sounds, a website which began as a spoof but now preserves some of the sounds from our technological past.
