I started a thread like this once before, but it never really got off the ground, so I'm going to try again.
I'd like to examine and discuss Ne in depth. What are people's thoughts on this function? What do you know about it? What throws the switch in your head that says "This guy is an Ne type" when you meet one?
I see Ne as a function of the desire to gauge potential in everything that one sees. That's about all I can think of right now.
