> If you want to treat your social media as a public journal that is cool, but not likely to make you an influencer

I think the key trick is you need to be interesting. A public journal can be for some people but probably not most.

I'm interested in a public journal of someone in the top of their field, thinking deep thoughts and explaining how they see the world.

I'm not interested in a public journal that amounts to: today i bought groceries and binged netflix.
