You'll probably want to put in an assortment of writings (representing both different styles and different moods), since certain aspects of the results can vary drastically depending on the sample analyzed, then take the median value. This page tells you what the results mean.
Now for mine! This was done quite sloppily (the "median" thing only occurred to me toward the end) and I may redo it eventually, but for now it suffices.
Five primary dimensions.
*Openness* Very high: very open to experiencing a variety of activities. [Very high? Seriously??]
Adventurousness Middling: I both enjoy my routine and am eager to experience new things.
Artistic interests Very low: less concerned with artistic or creative activities than most people. [Until my jaded adult years, I was quite artistic, so this result is puzzling.]
Emotionality Mid-low: Don't frequently think about or openly express your emotions. [As opposed to "emotionally aware". This one seems a bit off. My emotions are somewhat stunted by my meds, which might be having an effect.]
Imagination Very High: I have a wild imagination. [Versus "You prefer facts over fantasy." The fuck?]
Intellect Very High: Open to and intrigued by new ideas and love to explore them.
Authority-challenging Very high: Prefer to challenge authority & traditional values to help bring about change. [Sounds about right.]
*Conscientiousness* Tendency to act in organized or spontaneous way. Low score.
Achievement striving Low score: content with level of achievement and don't feel need to set ambitious goals. ["Content" isn't how I'd put it...]
Cautiousness Mid-high: Think somewhat carefully through decisions before making them.
Dutifulness Low: "You do what you want, disregarding rules and obligations." [That description doesn't hit home, exactly.]
Orderliness Low: Don't make time for organization in daily life.
Self-discipline Very low: have hard time sticking with difficult tasks for long period of time.
Self-efficacy Middling: Don't have a consistent feeling about my ability to succeed in tasks.
*Extraversion* Tendency to seek stimulation in company of others. Low.
Activity level Low: Appreciate a relaxed pace in life.
Assertiveness Low: Prefer to listen than talk, especially in group settings. [In group settings, this is definitely true.]
Cheerfulness Low: Generally serious and don't joke much. [I suppose there is a certain earnestness even to my jokes, so I won't argue with this.]
Excitement-seeking Mid-Low: Prefer activities that are quiet, calm, and safe.
Outgoing Low: Private person who doesn't let many in.
Gregariousness Low: Strong desire to have time to myself.
*Agreeableness* Tendency to be compassionate and cooperative toward others.
Altruism Low score: More concerned with taking care of self than taking time for others.
Cooperation Middling score: I generally veer on the side of avoiding confrontation, but sometimes contradict others.
Modesty Low score: I hold myself in high regard and am satisfied with who I am. [This one is utterly baffling.]
Uncompromising Low score. [Not sure what my low score here means, when consulting with the documentation... Low on "uncompromising" itself should mean I think it's wrong to take advantage of others. Which I do.]
Sympathy Very high score - empathetic. I feel what others feel and am compassionate toward them. [Seems a bit optimistic...]
Trust Low: Wary of other people's intentions and don't trust easily.
*Emotional range* Mid/upper-high: extent to which emotions are environment-sensitive.
Fiery Mid-high: Fiery temper, especially when things don't go my way.
Prone to worry Mid-low: Tend to feel calm and self-assured. [Now that's just bullshit.]
Melancholy High: I frequently think about what I'm unhappy about.
Immoderation Middling: Sometimes self-controlled, sometimes hedonistic.
Self-consciousness High: Sensitive about what others think of me.
Susceptible to stress Mid-low or mid-high: Can be calm under pressure or easily overwhelmed.
*Needs* Describes at a high level which aspects of a product are likely to resonate with author or text.
Challenge Middling: The urge to achieve, succeed, and take on challenges.
Closeness Mid-High: Enjoyment of being connected to family and setting up a home.
Curiosity Mid-Low: Desire to discover, find out, and grow. [I'd expect this to be higher.]
Excitement Mid-High: Want to get out there and live life, have upbeat emotions, and want to have fun. [Definitely too high...]
Harmony Mid-High: Appreciate other people, their viewpoints, and their feelings.
Ideal Ranges 37-82%: Desire perfection and sense of community.
Liberty Mostly high: Desire for fashion and new things, as well as need for escape. (The "escape" part fits.)
Love (Median: 27) Enjoy social contact, whether one-to-one or one-to-many.
Practicality Mid-high: Have a desire to get the job done, a desire for skill and efficiency, which can include physical expression and experience.
Self-expression (Med: 36.5) Enjoy discovering and asserting their own identities. [Seems a bit low.]
Stability (Med: 60.5) Seek equivalence in the physical world. They favor the sensible, the tried and tested.
Structure (Med: 57) Exhibit groundedness and a desire to hold things together. They need things to be well organized and under control.
*Values* Motivating factors that influence the author's decision-making.

Self-enhancement M62.5: Seek personal success for themselves.
Self-transcendence Mid-high: Show concern for the welfare and interests of others.
Given my inability to score high or low on certain categories regardless of what I fed Watson, I would say that the algorithm is measuring certain tangibles and shows definite promise. But in various aspects, it clearly has a way to go. I'm curious to see how it fares against some of you folks.
