I was curious to know what exactly is involved in VI typing. I have to admit I'm a little sceptical, but I guess I also don't know how you go about it either. Is it looking at physical characteristics (size/shape of eyes, nose, that kind of thing) or is it more kind of behavioral (like he looks aggressive, she seems deep in thought like she's not really there, etc)? It's just that I notice a lot of VI posts and I wondered how seriously everyone took them (is it something more like a hobby or are there convinced believers?).
