Yeah, the onboarding of most apps doesn't really help either with that humongous difference. 

I'm surprised looking at thread length wouldn't have an influence. That's the first crude algo I'd use to find actual conversation (like this one) 

 Well, length alone would strongly favor a GM post. Only measuring depth/width/nesting, would uncover interaction. 

 Yes! That's exactly what I mean with "length" (oops 🤦)  

 Oh, okay. I don't know, if they've taken this into account.
