A thing wish there was: a hashtag I can follow where people talk about their current weird fixation. One place I can click to learn about the history of Saturn's rings, or the ecology of moss, or how trains work or something. I love finding those threads/TikToks/etc and feel like a place to find them more easily would be cool. Like #followfriday but instead #currentlyobssessedwith and I get to benefit from their joyous deep dives.
