Also, I guess give Zuck time. He weathered the Snapchat storm and left them far behind.
Arguably a nicer 2.0.
Super addicting.
From my limited exposure what I'm seeing is that a ton of millennials are on TikTok making funny videos. I mean, TONS of people in past weeks. I checked it out maybe a year or so ago and it was all teenagers, but now it's millennials which btw are the users that made facebook/instagram what they became. So far it isn't laden with ads, the UX is very simple (1 video at a time and that's it), it's owned by a massive Chinese conglomerate with deep pockets and a likely appetite to take on FB.
edit: as someone else said the feature that makes it unique is the ability to use the audio from anyone else's video. They also have a large catalog of existing audio to choose from...
