"But writing about it is time consuming."

This, right here. Anything that requires research, planning, or deep knowledge, is an "unnattractive post" because the reward for that effort is too low.

There are other topics or styles of post that require much less effort and receive more reward. This is what I meant about feeling like I'm being nudged: write about this, not about that. So we all subconsciously drift toward where there is the most reward for the least effort...

("Reward", not just in zaps, but it discussion with humans.) 

 Humans attention is worthy and how you pack it is important to reach it. 
But also, one can only acknowledge the effort you put into something, filtered through their values. It’s disappointing yes. 
Deep thoughts are valuable, but also it’s sometimes valuable for us to enjoy life and don’t always think. To just stop and smell the flowers. But yeah you’re right, it seems like the more work you put in the less rewards you get. The best you can do is sell your words as good as possible, if you want to reach many people. Don’t give up!
