I always tell people, hey, I'm not a bot here posting things, I'm trying to share things I feel you guys would enjoy. If nobody comments, it doesnt incentivize me to continue posting, it makes me feel like a crazy person talking to themselves. I encourage people to say something, even if it's just "I really enjoyed this, thanks for sharing!" or something. I do that from time to time on others' posts. If they're showing me something new, of course I don't know anything about it coming in, but I can let them know now I do know thanks to their contribution here.

All these posts pop up all the time, "dang, it's so dead here" but if instead of making, liking, or commenting on that post, you could thank someone that did post, or share something that you think others might like. I was never a poster on Reddit. I'm no expert on what I post on. I just find stuff I think people would like, and now after doing it for the last few months, now I do know a lot more and can give people better insight than I could in the beginning.

Comments have been feeling low on my posts, and I think when is the point where me making 2 or 3 posts a day isn't worth my time anymore, but then someone will say "oh this post really made my day" and so I come back the next day and post again.

The fact you possess self awareness puts you above a great deal of people so please comment more often

I never let that stop me!

Well, comment anyway. You never know what’ll happen.

And even if you have a boring, vanilla opinion on that topic, post it anyway. Because it’ll lower the bar for others to comment as well. (As this entire thread demonstrates)
