nah...It DOES WORK...if you're good at sensing. especially extroverted sensing.
well...I'm sorry I guess it works only for certain types..hehehe (<douchey comment)
lemme make my point:
last 3 girls I've been with, I've visually typed from a distance...and been completely accurate.
now everywhere I go, everyone I meet, I visually type.
and then I find out, by getting to know them..if I'm right.
and 90% of the time, I am.
it works...just work on your Se, I guess
