Hello, @jrswab, you sound like a genuinely down-to-earth and warm guy. Pleasantly surprised to see your podcast (trending, no less!) as I was posting my poetry reading, on @dsound.
My niche, over these past few months, has largely been poetry, with some prose essays from time to time. I prefer to mix things up, somewhat (to hold my attention, at least :) and do it, naturally, not by scheduling days of the week, etc.. Also, I try to focus on quality, 'evergreen' content, as you say, and trying to network, effectively.
I find that I'm doing better over time (curied a few times, ocd, too as well as prizes, etc...) and reaching a wider audience. But, it's still not a reliable thing and I'm wondering how I can take it to the next level (without paying to promote my posts)?
