Now that YouTube has shorts I wonder how many creators are switching. Part of the reason you can get so many followers on TikTok is the video length. When it started you could only post a 15-second video. Later on they allowed you to link 15-second videos up to a minute in length. Then it was 3 minutes, and in February they changed the maximum video time to 10 minutes.[1]

Viewers can watch a lot more 15-second or 1-minute videos than 10-minute videos. If 5-10 minute videos start becoming popular, expect the reach new creators can get to drop drastically.
