Yes, I totally do. It makes me think I roll INFP.
Infact, reading through a bunch of old threads last night, I stumbled across predominantly INFP threads.. and almost every single post written by an INFP was written in a manner, using wordage, and coming from an angle that I personally would use. I'm not saying that all INFP's agree on ideas, infact... oddly.. when an INFP disagrees with a value of mine, it tends to grate on me more so than any other type I've disagreed with. Isn't that strange? It's almost as if I can follow the INFP's process and communication SO well, that when the finality of that Fi judgment hits, and is different than mine, it bugs.
I follow ENFP's as well, but I have noticed somewhat of a difference in communication and angle. I can't succinctly explain this though. The INFP writing or catch phrases that really stick out, to me, are things like
"Personally," "But thats just my opinion," etc. I RARELY see INFP's go to blows with people on forums. They will state their perception (always clarifying it is their perception) and when disagreed with be extremely diplomatic in their rebuttal. If another party punches low, throwing out some bizarre personal attack, I see INFP's typically bow out. I also see this as more of a "not willing to drop to this lowly state of attack" than a "can't defend my stance" issue. It's just not worth it to the INFP.
ENFP's on the other hand, are much more likely to stand their ground, take a personal attack and kick one back, or call someone right out on being a douche. There is usually a playful, sometimes arrogant feel to the ENFPs writing. When the ENFP is being challenged, there is an incredibley hard-nosed, stubborn vibe to the writing. I can almost feel the ENFP shove that Fi way down.. and pull out the Te bitch slap. The ENFP will be strong and somewhat logical, but not ALL their reasoning flows with logic, so it makes them more susceptible to others critiques.
INFJ's move with Ni well in their posts, sticking to a fairly close proximity of topic, but going deeper, and deeper. Essay style. INFJs will analyze every detail of a scenario.
ENTPs usually have clever one liners. A brief, yet signifigant summary. I get the impression that ENTPs post more so for their own amusement than info gathering. I rarely see ENTPs stick around if discussions go too deep, or become "ugly." I also rarely see ENTP's insult other members, always holding to a charming or playful vibe.
INTPs will sometimes have a strikingly similar writing style to that of the INFP, yet their angle is logical. I notice that alot of INFPs will comment or feed off an INTPs analysis, in agreeance, and visca versa.
When an INTJ posts, they usually tackle the very root of the topic. Clear and unwaivering. Succint. Their mind is made up. Posts are saturated with such a logic and confidance that even if they are wrong, they are rarely challenged. And if they are challenged, they could care less. These are the ones that make everyone else second guess themselves. =)
ENTJs are bold in their posts. They could care less for the topic at hand, but if challenged they will always fight back.
Anyhow, like an INFP might say, this is *my take* on some writing styles *I've observed.*
