Somehow I have yet to touch the app. I looked at the website once to view a video, but I’ve never browsed the site or made an account. Even my mom uses the app (and she’s a good 40 years over the primary demographic). I just have no interest in using the app. If I want to watch short memey videos I’ll just use YouTube. I’ve used it for many years and, despite its many problems, it still works.
Tiktok got banned in my country a long time ago. I can't say much about it being overrated or underrated because I was still very new to it and then it just became illegal here. But I guess if the content is entertaining enough, I don't mind the app. Instagram reels (basically the same) are my best way for passing some time, and it's fun if I come across fun reels, otherwise it's cringey.
