LA posted this in the thread I quoted Synarch from. Covers it very nicely:

The subtypes are based on the idea that within a type, individuals of that type will be disposed to focus on either their dominant or auxiliary function. There is also a balanced subtype. This produces two main subtypes, with the third falling somewhere in between the two extremes. These are my descriptions of them:
This subtype of INFJ appears quiet, serious, and somewhat shy initially, but can open up and be very outgoing, verbose, and witty. Likes joking, laughing, and discussing ideas with a small group of people they are familiar with. Can be mistaken for an extravert. Is somewhat possessive of those they love, including and especially their friends and significant other. Can be a bit moodier than the other subtype, and may manifest a great temper when angered or offended. Is often interested in mysticism, the occult, and other symbolic studies, and is original in thought and behavior. May speak metaphorically and is inclined to abstract and figurative thinking. They are also often absent-minded, dreamy, and immersed in their inner world. Likes to advise others and are full of new concepts and ways of seeing the world; observer of people. Their primary interest lies in upliftment of self and others, and finding a "higher" understanding of life through study and the sharing of innovative and progressive ideas.
Often of Enneagram type 4w5; high Ni types inclined to 4w3
Often attracted to extraverts, especially ENFPs and ENTPs
This subtype of INFJ is serious, well-mannered, and diplomatic. Prefers serious conversation and rarely, if ever, jokes. Has a calm and passionless presence, and can come off as cold and reserved. Can be mistaken for ISFJ at first meeting. They are prudent in offering opinions, but when they do are very insightful. Is skilled in handling wide varieties of people and can be found giving one-on-one advice. Common occupations include teacher, librarian, psychologist, or social worker. Often religious and/or follows a system of morality. Abhors injustice, violence, and conflict, and sticks up for the underdog. May come off as pedantic or self-righteous. They are hardworking and responsible, and emanate great wisdom and life experience even when young. Seem down-to-earth, stable, and graceful. Some are interested in humanitarian issues and/or alternative lifestyles.
Often of Enneagram type 9, with a possible wing type of 1
Often attracted to introverts, especially INTxs
In different discussions I have had with others it's been noted that there are what was termed the librarian style of INFJ (though that sounds slightly pejorative) and the more bohemian/arty INFJ.
This is interesting, I think I identify much more with the first one - but I work in a library like the second one mysterious.
I'm pretty sure I know 2 or 3 infjs (after complaining that I didn't know any and trying to find some) now ... but still they seem nothing like me, unless that's what all infjs think. They are much more conventional? I suppose than I think myself to be and a lot less silly or into strange/geeky things. Maybe I just hang around with too many in_ps good times.
So I am yet to meet someone who feels similar to me. I was excited, I answered this ad for an infj coffee group (whoa) someone wanted to started and they never emailed me back
