First and foremost, as a non-Instagram user, I flat-out can’t use it. A while back, when I was curious about TikTok, I downloaded it and was instantly swiping through a video feed that was already getting customized for me. I downloaded Instagram this morning and was presented with a wall to create an account. Nope.
Second, TikTok is new. Instagram is old. Young people want to use the newest social app that old people haven’t yet infiltrated.
