Paul, I think you are the first person to ask this question. Which is practically something of utmost concern for individual writers who want to be compensated— justifiably — for their stuff they have invested time and labor into.
I think that the new publication-focused ecosystem has little space for individual writers. They have just two options: either to join some publication which may or may not pay him, or to publish his own publication under the “Medium” corporation in which case a writer ceases to be a writer and becomes an editor or something.
Chilly, cheerless ,days ahead for those who hoped to earn in individual capacity from writing serious stuff on Medium.
I’m afraid individual writers would soon be a vanishing tribe here in the new ecosystem.
