TikTok turns it up to 11 in my experience. Facebook, Twitter, Instagram and YouTube all started off with a mechanism where you choose whose content to view through following/subscribing/friending. Over time, this was de-emphasized in favor of algorithmic recommendations, but it's still a strong signal. On the other hand, following on TikTok feels like an afterthought - it really aggressively recommends content based on the slightest interest. TikTok's algorithm is strikingly good at identifying what you like and keeping you there. YouTube also tries this, but it seems to be less effective at it and just degrade to showing you videos for the extremes of your political leaning rather than say, how effectively TikTok figured out what I find physically attractive.
