> Everyone thought Vine was here to stay too.
Vine was loved and was shut down by a part time CEO.
> Snapchat was huge at one point and now I no longer know anybody who still uses it.
People under 25 still love and use snapchat.
Tiktok has 80 million MAUs, and is becoming the tool of cultural influence in the same way the Instagram did. I wouldn't underestimate the staying power of tiktok.
