That shift is the focus of a new preprint that Törnberg co-authored with University of Amsterdam colleague Richard Rogers. “When we talk about social media, there are certain assumptions about what it is,” said Törnberg. “It’s user-generated, and there’s a platform that organizes interaction, but the platform cannot produce content on its own. So instead the platform allows people to connect with each other, and it just provides infrastructure for that. The [terms] social network and social media is almost synonymous. Those describe pre-algorithm Twitter circa 2012 quite well.”
