It seems like a total crapshoot to me.
I've gotten zapped for just sharing what I'm doing today and had other posts with insight, a bunch of research and cited sources seem to go unnoticed.
I think it's a combination of two things:
1. I don't really know what people value
2. If people don't happen to check their feed within minutes, or at most hours of when I say something clever, they'll never see my post
It's reasonable to value humor. I've zapped things that made me laugh. The things I zap the most consistently and the hardest are good answers to questions I posted. So if you want my money, now you know how to get if. 😄
