I never used tiktok much either, but I’ve been really enjoying rednote so far. As for attention span worries, it might be hit or miss for you, depending on what worries you. Much like tiktok, rednote is also mostly scrolling through lots of short videos, so that part is the same. But I’ve found the algorithm to be surprisingly good at giving you what you want. My feed is mainly lots of cooking videos, cat/dog videos, cute little cartoon frogs, badass communist imagery, outdoor/travel stuff, etc. I find it much more wholesome and less brainrotty/doomscrolly than tiktok. Every time I went on tiktok I felt like it only showed me people sitting in their car ranting and clips of right wing youtube assholes. I’ve seen almost none of that garbage on rednote.
