For what it's worth Auburn, I've always thought TA was inferior N. The way that he gets so enthused about generic abstract concepts like meta have always struck me as either drug-induced or part of an inferior grip.
As for THD, I've thought the same about his Ne. It's so sporadic and unpredictable, and he barely exudes a shred of Ti. Contrast with Spiralhacker, who I'm about 98% certain is an ENTP - you can see the possibility-analysis loop in Spiral. With THD, it just seems like unruly abstraction for the sake of abstraction. Though I kind of have avoided making any point about this, since THD is schizoaffective, PTSD and induces a lot of substances. I don't know how much of his unadulterated abstraction comes from this. Still, I have my doubts about him being an Ne-dom.
In general, from the Ne-doms I know in real life, they're a lot more blase about abstract concepts. They grasp them easily and they're not actually, "exciting" to them. At least in the way they seem to be to TA and THD. The concepts they talk about are so obvious that it's like, "why even get excited over this?".
Something I found interesting was the interaction between Brontosaurie and TA in TA's, "meta structure" thread. TA thinks he's stumbled onto something exciting, but to actual intuitive lead/aux's, it's just every day stuff. I think that's what Bronto (and Absurdity too) were trying to communicate in some ways - "Damnit TA, this stuff isn't as profound as you think."
Real N-doms from what I can tell, don't really get so over-excited by abstract concepts - because they're just part of every day life. They understand them and realize their significance, but I find they have a much more relaxed, conversational way of expressing these things. There's not that air of, "hypo" when they discuss them.
tl;dr - I find 90% of what THD and TA post to be redundant tautology, things that are so obvious they don't even warrant discussion. So I doubt them being N-dom.
Then again I'm pretty sure at least 70% of this forum are not the types they think they are based on similar criteria to the above. Either that or I just don't understand how people can get excited over concepts like, "meta" when it seems like it'd be so basic and obvious to any intuitive, to the point that discussing it feels like tautology.
