What sold me on Tik Tok (I'm a early 40 year old guy!) was realizing how their algo allowed you to drill in to a musical emotional trip like no other platform that I've seen to date.
You find a video, with a song, that you vibe with. Now, click on the bottom right sound graphic and you can watch ALL the videos produced with that sound and vibe.
It is part of the core product!
So good it's hard to describe :)
