I mean, to be slightly pedantic, TicTok is not a horrible design. It is a genius design with a horrible purpose. It’s genius because it’s extremely successful at its core purpose: driving engagement metrics for ad revenue. In terms of raw engagement, an endless stream of videos injected into your brain is way better than something like YouTube, where you’re normally doing some “heavy lifting” to curate your own content via search or subscriptions. TikTok is probably the best implementation (so far) of an addicting content consumption platform. By “best,” I mean it has the best engagement metrics.
