You have to engage the community if you want more and more people to curate your work. It takes time. Sometimes, a long time. It's a grind so-to-speak. You need to keep putting yourself out there. I only started making returns recently this year. I must have put out 60+ articles before I started seeing something worthwhile.
I'm not even selling my POB yet. Aside from staking most of it, I've just been using my earnings to support a contest. The rest I still stake. I'll probably continue doing so for the next couple of years.
