Agreed! I downloaded the app, saw 10 minutes of teenage girls dancing, and deleted it. My friend talked me into giving it another chance. After a few hours, it was consistently delivering videos that were exactly my taste. I've never had such a good discovery experience.
afaict it uses engagement to determine what you like, so
- watching the video completely
- liking
- commenting
- sharing
increase your account's affinity to the tags associated with that video. If you like multiple videos with the same tag, you'll start seeing many videos with that tag. So, I think searching for a few tags about topics you're interested in and liking a few videos will prime the algorithm enough to make suggestions start being relevant.
This can also be annoying - I must have liked a few vids about dnd, and now i get more dnd suggestions than I want.
I love when people complain that Tik Tok is just teenagers dancing. That tells me you haven’t really spent time on the app or the algorithm has determined that dancing teens keeps you engaged.
