Con. The algorithm seems to dish out similarly structured videos for all users. For example, it generally includes music that is extremely annoying. (That "No no no" song that is on every other video). At the same time, I also recognize how addictive the app is and because of it I would never download it myself.
I get "No no no" videos but when I mentioned them to my friend who is using TikTok a lot she had never heard of them. I presumed that was too big of a trend not to leak into everyone's For You feed but I was wrong.
This is why I stopped looking at TikTok altogether. "Trends" just seem to be too enormous a use case for creators, to be avoided. I never wanted to know who Megan Thee Stallion or $NOT are, but here we are.
