Writing about Medium was a quick ticket to the "not distributable" pile in the early days of curation. Now, who knows? We stopped accepting stories about Medium in The Writing Cooperative years ago because, as you said, enough is enough.
However, as the popularity of this article proves, people still want to write about Medium. Maybe the algorithm favors "negative" stories like Facebook's allegedly does. Or perhaps humans are just glutton's for punishment. Who knows?
Either way, the irony of writing a viral article about not writing about Medium is like Medium-inception.
