Hello Proxy: In this new clip we talk about the digital traces that we leave on the web when we browse and use web platforms. These traces tell a lot about us: by analyzing them, platform owners can create profiles of their users. In turn, these profiles can be used for many other activities, for example, to provide automatic recommendations on what to see, listen to or buy; even on which other users to follow or with whom we might become friends. Wow … Enjoy!
