I'm creating mostly in a few social media. That make me connect only with certain niche of people. I started to try more and more social media and I understand that creating in only a few social media may have a negative effect on us.
That's why I will try to improve my existance in more social media. It's not only about the earnings, but about the improvement. When someone creates in only a few social media, he/she learn about those and that's it. It's impossible to have the full picture of things that way. For example most people know about the coronavirus only from the mass media, but if they will check the information in other social media, they will all find an other truth about that.
The good thing also of being in as much social media as we can is the promotion and support. More people will know us this way and it will make them much better when they support our content, maybe that's because the trust of the creator. That's why when you see famous people joininig anywhere, they get support even if they have no influence or if they didn't invest a cent in there.
So, the goal of each creator is to assure a good existance in as much social media as he/she can. Only that way we will be able to never give up on something we started !
