Also, something very weird I've been noticing lately, if you take a glance at my latest posts, when I spend hours selecting photos and writing and sharing something interesting, I get less upvotes than posts, where I just share few of my travel photos. It's like the community is trying to tell me "don't waste your time here". Rewards have so little to do with content...

I notice the same. I get much more interaction on my shorter ones where I'm just sharing my thoughts as well. I've been writing up some longer posts on biology, health and chronic disease prevention from my own research that I thought I'd share, but I think if it's not of interest to the majority then they don't want to be spending that much time reading it, despite the fact that I think it's useful.

The same probably goes across all social platforms. I'm often surprised at what gets more attention on Instagram from my posts and my daughter pointed out that while some things might be easy to do for me, they look more showy to others. The showy bit also needs to be at the start of the video. 😉

There's also luck of the draw as to which accounts find your post and vote on it here, I suppose.
