Why isn't there a social network only for video?

There are many.

Tiktok. YouTube. Take your pick.

Social on youtube is cancer. Tiktok is cancer entirely.

The question has nothing to do with quality.

There are good groups on Youtube and bad ones just like any social platform. Humans can be cancer is the right observation.

What is groups? You mean channels?

tiktok is literally shit yet addictive.

Because Twitter killed it

Isn't that Instagram?

Snapchat?
