Ethereal has a stronge sense of asthetics and for rhythem in music, remember. Fi also comes with insight, it's not exclusive to N, and if it is dominent the S part will be less pronounced. Anyway, if Ethereal feels that is the better fit, I trust his judgment. I wish him luck as a newly minted ISFP, but if he wants to be an ENFP, I'll acept that as well. (I say again, we miss you Ethereal, your loss leaves us confused and desolate.:crying
I do not know about the Carnegie Mellon thing...if you mean my avatar theory, that's just a vague idea I have from my observations. Your avatar and signature are ways to tell people about yourself, like clothing in real life, so I think what people choose can be quite telling...yet, like clothing, it can be decepetive. It at least says something about how you wish to be viewed, or don't.
Our masks say a lot about the people we are behind them.
