Reading your website now. All the more exposure, all the more to learn.
I do disagree with your assessment of Myers-Briggs and DiSC, however; perhaps that's because of my exposure to them differs:
I've always seen Myers-Briggs as an example of self-discovery, rather than putting others into a box. i.e. "Are you aware you do these things?" with the answer often "No" or "Actually, I thought I was the opposite." My first company did it for everyone in the on-boarding 2 weeks training/induction period. It was useful for self reflection.
DiSC: Every training I've been exposed to started really clearly with a line like "This is a tool for understanding people and their environment. Your home and work environment, for example, are probably different, and so is your communication in these environments. Likewise, your work environment changes over time and role. DiSC types are not about putting people into a box, and people are not a single type, but a combination of types with stronger weightings in some areas."
Myers-Briggs is totally ascientific and could be thought of as self-discovery in the same sense reading tea leaves is.
Myers-Briggs has been repeatedly found to have no reliability or validity as a personality trait assessment and has been totally superseded in psychology research by the OCEAN metrics, which are empirically developed.
Ironically, the only place I still see MBTI used is in computer science papers.
