Does he? I think he's about as INFP as it gets, but my perception may be colored by a larger number of interactions than your own.
Well see, here's the situation. Most of the time when I'm logged on, I'm here in body, but not in spirit. I only pay attention to about 10 people on this forum that are interesting. I just started noticing him about 3-weeks ago. I think he posted something in the "Ask an ENTP" thread.
