Alright, here's the dealio. I find most functions relatively easy to spot. There are some telltale signs of each function. However, though I understand what Ni is, I find it really hard to actually point it out. I pretty much never say things like "oh that guy's using Ni" though I can do it with the other functions. Can you guys point out some things that Ni specifically users say or do the should serve as clues to us?
