Hidden Information, Spontaneous Information and the solo RPG experience

I often make pretty random posts which are more like a way of trying to synthesize things I'm thinking about, or reading about, in my quest for a satisfying solo RPG experience. 

A discussion at the Story Games forum regarding games with "Hidden Information" got me thinking about the opposite concept (spontaneous information/non-existent information) and their relationship to each other. Of course, I'm also interested in their relationship to solo gaming, though I didn't focus specifically on that aspect while participating in that discussion. Here is my attempt to apply some of what I got out of that to solo rpg'ing.
