Right out the toaster. Reliable, with some real depth.
Summary
Analysis of U.S. social media trends from 2020-2024 using ANES data shows overall platform use declining, with youngest and oldest Americans increasingly abstaining. Facebook, YouTube, and Twitter/X have lost users while TikTok and Reddit gained modestly, creating a more fragmented digital landscape. Platform audiences have aged and become more educated and diverse. Politically, most platforms shifted toward Republican users while remaining Democratic-leaning overall, with Twitter/X experiencing the sharpest political shift. Political posting remains linked to affective polarization, with most partisan users being most active, leading to a smaller, more ideologically extreme online public sphere.
