Well, INTPs are rare and typically misunderstood and oppressed (often unknowingly). Like all afflictions, INTPness brings it's sufferers together. Also, INTPs seem to me, the most likely to enjoy pondering MBTI, and personality in general.
Almost all of the above also applies to INFPs... their forums are just more... um... shall we say
less civilized?
lol I like something I saw in one of the other INxx forums (don't remember which one, now) about ESFJs... "the world is their forum. Why would they be here?"
There's also 2 I know of that try to blend all the personalities together. I'm only active on one of them, and there's an ESTJ there... lol but I think he's mostly there to learn how introverts work so that he can understand his brother better and know whether his "constant withdraw" is normal... no ESFJs yet (surprise!).
I don't know about ESFJ forums, but there is a member of intpforum who is a friend of mine, and
is actually an ESFJ. His user name is... wow! I totally did not do that on purpose! His username literally is "ActuallyAnESFJ"! I mean, he only came on here, like, once, and he didn't post anything... but still. I think it should count for something!

I know for a fact that he goes on some other forums a lot, though, but those have nothing to do with personality.
But he really does just prefer getting out there and meeting people, and doing things, you know?

So, which types
do have the best forums? I bet INTPs have the best technical forums, at least...
