TikTok's algorithm is also nearly instant.
From time to time it will show you content adjacent to what you watch. After three or so viewings your feed will add the content you watched/engaged with regularly.
Press "not interested" twice (or sometimes once), and content will disappear.
American social media effectively ignores any input from users.
so much this. tiktok can easily be trained to provide you pretty much exact content you desire from it while no other social media platform (is willing) can do the same
