What I find strange about TikTok are the waves of themes I get to see. Being a 50-something I'm probably not the target audience but at first all I saw was shuffle dance (enjoyed that) followed by Indian and Chinese manufacturing videos (loved those) and now it's all cats (okay with that).
My daughters explained "Elite TikTok" and "Beans TikTok" so now I realize there's a whole world built on top of gaming the algorithm in order to bolster your insider status.
