Part of me wonders though if TikTok is helpful in understanding recommendation algorithms and curation, because it’s so blatant. I notice that, especially with younger users, there’s a total understanding that what they’re seeing is not occurring naturally, but is the result of computational choices being made for them.

Users also create reaction videos to other videos, showing a selfie shot next to the original clip. Everything is participatory, and the nature of the algorithm makes it so that a video from an unknown account can go as viral as easily as one from a famous account.
