This is hilarious!
I'm ranked first in:
Cheerfulness (Before or after morning coffee?)
Orderliness (Because of my 3rd normal form sock drawer?)
Gregariousness (Before of after my 3rd beer?)
Agreeableness (I disagree! Watson needs debugging.)
I'm ranked dead last in:
Imagination (No one I know could imagine how this could be.)
Authority-challenging (My teachers & bosses would disagree.)
Intellect (Before or after my mother dropped me on my head?)

Its not a top by category ranking of all HN posters, there's a merged list of top commenters and leaders, and then the ranking is from that. Being on the bottom of that (as I am for agreeability) doesn't mean you are still ahead of everyone on HN that didn't make the list.

Hi. I built a Chrome extension for Hacker News that lets people follow others and get notifications when they are replied to or their karma changes. http://hackbook.club
The ext basically matches my original vision now, so I'm thinking hard about what features to add next, but I'm not quite sure I understand what you're asking for. Are you saying that when the extension says "So and so replied to you", you want, say, a sympathy score shown with that user as well?

On one level it could be a simple bookmarket (bookmark with JS). When clicked, it goes through the HN discussion page. When it finds a top HNer's username, it (1) colors it and (2) shows the category if that HNer is in the top or bottom 10% in any category.
For instance:
edw519 33 minutes ago | link
Top: Cheerfulness, Orderliness, Gregariousness, Agreeableness
Bottom: Imagination, Authority-challenging, Intellect

Ok this actually makes a lot of sense. When someone replies to you on Facebook, you generally know who they are. On Hacker News, you have no idea. Including some basic (albeit imperfect) information along with a notification reply could be really useful.
This could even be true for the follow-feed mechanism. If you're following someone on Twitter or friends with them on Facebook and they write something that appears in your feed, you are already familiar with the author on some level. In the Hackbook extension, it's fairly common to follow people and not know much about them at all. Again, including some basic Watson-generated information along with the "a user you're following wrote a comment" newsfeed item could be helpful.
Let me give it some more thought and maybe I'll have time to work on it this week.

One of the difficulties this kind of output has is that it runs very quickly into issues of semantics and model labeling.
We humans each build models kind of like these when we interact with one another, so when I ask somebody, "do you think <name> is an agreeable person?" and they reply "sure I think he is!" they're consulting that model to provide me an answer. Humans can even do a kind of pairwise sorting on that model and tell you if person1 is more or less agreeable than person2.
However, even if our individual models may differ a bit, and the results of these kinds of questions to each other might differ a bit, there's an inherent "humanness" to the results because people generally have a pretty similar semantic understanding of what "agreeableness" means.
However, what does Watson think agreeableness means? I have no idea, nobody really knows. Watson can't really explain it. All we know is that there's a model that produces a scored (and thus rankable output) when asked to score a corpus on that model and somebody somewhere labelled that model as the "agreeableness" model, perhaps based on some heuristics or parameters that were intended to define that notion.
It's thus very hard for humans to trust scoring like this because when it doesn't make sense, it doesn't make sense for reasons that no human would have about the matter. For example, I would personally say pg is far more agreeable than I am, yet Watson scores our respective collection of comments exactly the same. I can't explain it, Watson can't explain it, and thus it feels "wrong" and now I can't trust the scores that Watson provides me.

Well, in a sense, most of us all only know each other through our comments, and that's all we can ever base an assessment like this on. By proxy we have to assume that when people's inner thoughts leak out into the Internet on a forum like this (and in a sustained enough way to make them a top-100 karma earner) that their aggregate corpus of comments will be a reasonable insight into who they are.
So for all purposes that you, I or Watson can demonstrate, "do you think X is Y" and "do you think X's comments show Y" are functionally the same.
edit
I just checked what Watson thinks are my needs. Apparently I don't have many, and everybody on HN has an extreme need for Challenge.
I almost feel like these results require a lot of interpretation, and that interpretation is about as reliable as a horoscope.

Cool app! IBM is in the process of significantly updating their documentation on User Modeling, but meanwhile, here are some basic descriptions of some of the traits, as well as links to some of the research behind the service.
User Modeling analytics are developed based on the psychology of language in
combination with data analytics algorithms. User Modeling extracts three types of
personal characteristics from the data a person generates in social media or within
their written/digital communications:
Big 5 Personality - This is the most used personality model that generally
describes how a person engages with the world by the following five
dimensions:
– Openness-to-Experience - associated with curiosity, intellect, and an
appreciation for art and adventure
– Conscientiousness - associated with organization and industriousness
– Extraversion - associated with positive and outgoing attitudes toward other
people
– Agreeableness - associated with compassion and cooperation toward other
people
– Neuroticism - associated with a sensitivity to negative emotions
Each of the five top-level dimensions has six sub-facets that further characterize
an individual at a finer-grained level.
Basic Human Values - this model describes motivating factors that influence a
person's decision-making. Our current model includes five dimensions of human
values based on Schwartz's work in psychology:
– Self-Transcendence - motivated by helping others
– Self-Enhancement - motivated by increasing social status
– Hedonism - motivated by pleasurable experiences
– Openness-to-Change - motivated by experiencing new things in the world
– Conservation - motivated by tradition and conformity
Fundamental Human Needs - this model is based on Maslow's hierarchy of
needs and Ford's work on Marketing and consumer-related needs modeling. It
describes, at a high level, which aspects of a product will resonate most with a
person.
– Ideal - the person likes high-end, finely crafted products
– Self-Expression - the person likes products that express their individual
identity
– Closeness - the person likes products that help them establish closer
relationships with family and friends
– Excitement - the person likes products that provide exciting, adventurous
experience
– Practicality - the person likes products that simply get the job done
For more detailed information about the research and technical background behind
the User Modeling service, see the following:

Basic Human Values - this model describes motivating factors that influence a person's decision-making. Our current model includes five dimensions of human values based on Schwartz's work in psychology: – Self-Transcendence - motivated by helping others – Self-Enhancement - motivated by increasing social status – Hedonism - motivated by pleasurable experiences – Openness-to-Change - motivated by experiencing new things in the world – Conservation - motivated by tradition and conformity Fundamental Human Needs - this model is based on Maslow's hierarchy of needs and Ford's work on Marketing and consumer-related needs modeling. It describes, at a high level, which aspects of a product will resonate most with a person. – Ideal - the person likes high-end, finely crafted products – Self-Expression - the person likes products that express their individual identity – Closeness - the person likes products that help them establish closer relationships with family and friends – Excitement - the person likes products that provide exciting, adventurous experience – Practicality - the person likes products that simply get the job done
