When I joined this site, the most notable thing for me about it was that the people I saw and/or interacted with who identified as INFJ were recognizably INFJ to me. What I mean by that is, people who, to my eyes, speak (write) clearly from a lived experience of having these cognitive processes in this order: Ni-Fe-Ti-Se.
I have seen other online contexts in which this is not the case - in which there does seem to be a lot of mis-typing as INFJ going on. In those contexts, there seems to be a fair amount of discussion focused on personality trait discussion among self-identified INFJs: "I'm [insert postive/special personality trait here], do you other INFJs relate?" followed by a discussion that has little or no relationship with actual INFJ cognitive processes, or gross misunderstanding of these processes by people who type as INFJ.
So, an upside to TypeC, for me, has so far been that the INFJ participants who have crossed my radar here do seem recognizably INFJ to me. The downside to this site, for me, is that instead of INFJ-exotification, this site seems to have a fair amount of acceptable INFJ-bashing. I don't think INFJ is exoticized here, I think it's more on the side of disrespected. These are IMO two sides of the same coin somehow, both of which aren't useful for dialogue and interaction. That said, I think I actually prefer a context in which we're disrespected/bashed over one in which we're exotified, if I have to choose. The reason for this is that I actually learn useful stuff from reading posts by other real INFJs rather than by people who don't have this function stack but want to be INFJ due to some assumed exotic personality traits.
Now, the above is based on what has crossed my radar in my participation here plus the poking around I've done in some of the archives. I've only been here for a month or so and there's a lot of info (discussions and participants) I haven't seen even with the archive poking.
Also, I haven't read through all the comments here, but given what I've read so far I can say that I tend to agree with [MENTION=20829]Hard[/MENTION] that the special snowflake thing would be related to enneagram 4 and not MBTI type.
eta: [MENTION=5494]Amargith[/MENTION], the background info you shared via rep was interesting, would you be willing to post it? (ok if not, just that I think it's interesting)
