niffweed made me think of something.
Firstly, you have the Starfall/glamourama kind. They're hotter than the other kind in my opinion, because they just shut the fuck up and do anything for you.
KIDIIIINGGG . . . (except that they are hotter)
No, they're generally quite quiet and passive, but there's clear interest there beyond the surface. They're a mystery that is worth cracking. Probably less male, more female. If they were a subtype, they'd be Fe subtype. They're primarily 4w3s.
Secondly, you have kind that I call the intellectual IEI. Loki, esper and my father all fall into this category of IEI. They're into their esoteric systems of thought (like the Enneagram) - in the case of esper and my father - or they write long, drawn-out yet extremely insightful posts - in Loki's case - about any given (metaphysical/philosophical) topic. This isn't to say the other lot can't be insightful, because they can; they just don't do it as often as this lot do. Anyway, these guys seem more comfortable giving out information on their area of interest, and they love coming up with new theories and ideas within said area. People value them for their wisdom. More males (even though, ironically, two of the examples I gave - Loki and esper - are both female) than females, as the intellectual interest draws them. If they were a subtype, they'd probably be Ni. I think they're mainly 4w5s.
