Niches only really matter if your motivation for writing here is financial. Some of us aren’t overly motivated by money - we just enjoy the process.
Making money is simple. Write about productivity, write about medium or write about giving blowjobs and other risqué content. Not for me. I show up, I write what I want and then I do it again the next day.
Won’t be a Medium millionaire, but will be here for the foreseeable watching the perpetual money-seekers meandering around on the carousel of despair.
May as well sacrifice a goat to the Great Algorithmia, as soon as anyone works out how to game the system. It changes. :o)
