I know I'm a bit late in replying, I'm guessing this won't be read - but oh well!
Typically, it is assumed that a typing represents the whole of the Self; I tend to use it only as a generalization of the Self.
Coming from a Jungian background, the psyche is composed of multiple (if not many) complexes. Each complex being an autonomous psychic entity but a component of the psychic Self.
Each complex can have its own typing. The Anima (feminine complex) could very well be an ESTJ and the Animus (masculine complex) could be a INSJ. The compound result of all the complexes results in the dynamic and volatile nature of the psyche.
This multi-faceted nature of the psyche produces a (to me) accurate view of the psychic Self; a person can too have a type that generally dominates the whole of the their psychic Self as well (ie: I'm an INTJ, my Animus is more of an ISTP and my Anima is an ENFJ - don't forget there are other complexes).
Also, MB typing is not value free. If something were value free it would not be of value ;) The difference between "introverted" and "boring" isn't in the value of each term, it is in the interpretation of the value of each term.
One could consider boring and introversion to both be an inward psychic motion. Boring - to bore - going within; is uncomfortable for many people because within their psyche they must experience their complexes as opposed to projecting their complexes and experiencing them outside of the psyche (with other people, things, etc...). Hence why "boring" is imbued with bad or un-associative thought.
Introverts tend to be internally focused and rarely engage in the projection atmosphere commonly seen with large groups of familiars or extroverted (to different degrees) people. When a person is not engaging in a projection that another wishes to engage in, the person not engaging is typically considered "boring" or "serious" or "anti-social".
Please note, neither extroversion nor introversion is better or worse than the other. Claiming and accepting the complexes of the psyche within leads to both a happier introvert (that is more extroverted) and a happier extrovert (that is more introverted). Just like claiming and accepting the feminine or masculine self leads to a more balanced individual; it just happens that one is already dominated by the other and finds it to be a natural setting. The above paragraph was using familiar language to convey a point, but was limiting in its scope.
All things have value, even if that value is unit value (or 1). Value is provided by the human mind and subject to valuing meme levels (context dependent).
The majority of Hacker News readers are in a mix of systemic (computers, systems) and entrepreneurial (startups, ambition) valuing memes. The Hacker News reader typically values the experiences they have within their life at this stage based on those memes.
