I used a couple of recent messages to two different friends. At first I got "Age: 22" and "99% Masculine" (and didn't look further), so I thought maybe I hadn't used enough words and copy/pasted a lot of messages from chats with several different friends.

Age: 25
96% Masculine
48% Leadership Potential
INTP

71% Liberal and Artistic
43% Impulsive and Spontaneous
28% Contemplative
37% Competitive
44% Laid back and Relaxed

It looks like the only things it got right are my age and that I'm not easily stressed.
"People who use language of this kind tend to be the epitome of masculinity!"


I tried this with some of my blog posts and got age 30, 61% masculine, 54% leadership, ENTP. and more balanced big-5.
