The best part for me is receiving some random emails from time to time with people saying they liked my post or poem or something else.
I don't have expectations for those letters though. Intentionally I don't have google analytics on my site. When I did have it, it influenced how and what I was writing.
Now I just write for myself. And if my writing happens to be valuable to someone else - it's a bonus. Mostly I write when I want to offload some thoughts about some topic. When I finish thinking about something, I write it down and that topic is "closed" for a while.
Also, what helps me to write and publish is my setup. I changed setup many times. When there was friction to write and publish - I rarely did it.
