Difference between random insights and random questions?

At the moment at least, I'm having trouble keeping track of all the crap tearing through my head. So, yeah, Gul Type Query again.

Rick described Ne-base as continually having "random insights" popping into one's head. What are "insights"? In my case, I constantly have unanswered questions that I want to try and fill... this is one of the reasons I was willing to accept ILE.
