“It’s been fairly well-documented that even when you are not proactively revealing much about yourself, your devices are, your browsers are, your behaviors are, so typically by nature of what you’re clicking on, what sites you’re visiting, how long you’re spending on them, social media companies can create a profile about you… because they’re detecting patterns in those behaviours of yours.” Professor @davidjmalan goes on ABC’s Radio National Breakfast to talk about the nature of social media algorithms and what their regulation could look like. abc.net.au/listen/programs/r…
