In all of the TikTok praise threads we've had here, this is the first time I can remember ever seeing anybody mention what I personally believe is a killer distinguishing feature. TikTok's algo guarantees that every video will appear on at least N FYPs. Then if it performs well in that ad hoc 'test group' it will be show to a wider group, and so on.
My friend posted a video of his wife stroking a cat on his brand new TikTok account and within two days got >5 million views and offers of sponsorship from cat food suppliers :D
Ding ding ding, yes, TikTok surfaces better content because of the nature of its recommendation algo. One of Facebook’s top priorities is now following in their footsteps — moving away from social graph-driven recommendations to AI-driven recommendations. Just listen to their last earnings call.
Using it to establish yourself is great, it's a means to an end, a marketing tool like the rest.
