Consider using Snapchat.
Snapchat has over 170 million daily active users and 10 billion daily video views. It’s a massively underestimated social network. It has remained among the top five apps on the AppStore for a long time.
On Snapchat, content disappears—it’s not permanent, and this makes it very special. That’s why Snapchat is the best platform to start on: because you can show your imperfections, you can make mistakes, and no one will remember it. You can post your throwaway content.
