I like it.
It has me as INTP.
However, I have a friend who first tested as an INFJ and then tested as an ISTP through the Facebook app.
He tested as a borderline N & F on the first test (with I & J being stronger) and tested as a borderline S & P on the second one (with I & T being stronger). I personally would say INTJ or ISTJ for him.
Another friend of mine who is very quiet tested as an ESFP- unless he's a quiet extravert which is a possibility S, F & P describe him well for sure though.
