As far as rewarding good content, I think POB does a generally good job compared to a lot of the other platforms out there. Having said that, the reality is that ultimately, when it comes to rewards, it is a function of how much 'stake' you can get onto your post.
For me, I like to see that the content is original and that the author has put some heart and thought into it. Whether it is a poem, cooking recipes or even art and crafts. Language isn't much of a consideration except for detecting something suspicious. But i'm not the biggest curator out there so take my words with a grain of salt.
I share your opinion. I like it when writers put their perspective on publishing. That way, the person have more personality, and not just become an informative or descriptive text of something.
