I think that the possibility of using tron's NFT in steemit is a bit far since the steemit team is focused on other things.

A couple of days ago I read an article that talks about a new social network that is based on the fact that your publication will automatically become an NFT, you can read it here.

El español Daniel Santos crea la primera red social descentralizada de NFT

I recommend you use the google translator or translate the page into your native language since the article is in Spanish.
