There is lot of good content creators on TikTok apart from (dancing/singing) ones, the TechTok community is huge , It really depends on what interest the end users have, It's all individual attention driven algorithm that caters to the end user needs based on their likes/dislikes. It's faster to learn if you don't like something it does a good job in not recommending those type of content again. Which I believe Instagram/youtube isn't that great at.
