I've been studying the MBTI for a year and a half. Funny enough was that I was introduced to it by two T types. I've been at it diligently ever since.
I just ordered "The art of speedreading people" and I've owned PUMII for a while now. I still need to get through that. It's a pretty interesting book I just find I'm more interested in my own development than the other types in general. The J in me wants to read the whole thing though.
Oh yeah, I've been on INTPcentral for a while. I guess I joined because I thought I could make some friends there but they're just there to have pissing contests so I came here!
P.S. is the admin an SJ? "An email was dispatched...!" LOL
