That’s your personal experience. But I can guarantee that if you rewind a few years you’d be able to find many people who would say that Snapchat gave them the kind of experience Instagram never did, or whatever. Snapchat was huge. TikTok is huge. But there’s no guarantee of permenance.
Snap never got to the level of TikTok and it was always really niche but mostly, it required IRL friends to send awkward Snaps too. TikTok doesn't have this limitation and is the lowest friction to entertainment social media ever. Of course, nothing is forever, even Facebook, but as far a these things go, TikTok was in for the long shot.
People don't realize how addicted a lot of people are to Tik Tok. It's scary in terms of thinking how much time is 'wasted', but in terms of a product, it can reach the popularity of Youtube.
