I actually like the site for the following reasons:
 one place where, I can observe so many INTJs at once (for my own study)
 they are the only mbti forum that tends to have a conservative stance politically. Even though I'm more left, I enjoy being outnumbered, and disagreed with - as it's more dynamic and challenging for me
 they tend to have less fluff per thread
 I'm one of the rare people, that like the longer, more well thought out posts (even if I don't agree with the content).
I dislike it for the following reasons:
 Mods are FAR too delete happy. Deleting any threads or posts they deem superfluous, many which I don't agree with. It makes the threads less dynamic and much is loss re: what people actually think (instead of the mod white-washed version). I have a suspicion the mods don't want the public to see how juvenile and idiotic some of their less intelligent members are..... which would reflect on INTJs as a whole.
 Most individual INTJs there, never change their mind on anything (no matter how much logic or evidence you give to the contrary). The INTJs here seem more mature for some reason. Maybe because the ones that would hang here, are less likely to be arrogant and think their type is the smartest or best (which is not very well concealed, by the majority of folks there).
 Their mbti analysis is weak and simplistic. I think MBTIc is the best site for analyzing MBTI. Mainly because people here do a better job of incorporating real life experiences; rather than paraphrasing stereotypes in the literature constantly.
