You focus on things people aren’t willing to post on their Facebook feed. Snap and TikTok remain strong despite being copied because it allows people to essentially shitpost without their close friends and family seeing it.
I wonder how VSCO is faring compared to Instagram, which is another similarly "anti-social" network. TikTok has the benefit of being owned by a larger conglomerate, ByteDance. Supposedly Pinterest was in talks to acquire VSCO.
