I see I'm not exactly in great company here so far.... I mean, if it says that I'm the most extrovert so far, what does that say about everyone else?
It means you feel a greater need to seek company, and express yourself, and are more likely to feel revitalized (rather than drained) with company.
That's the thing, though. I don't consider myself extroverted in that in real life I usually keep to myself - even during break times at work and during the times after work and in weekends - and I don't usually socialise or go out for drinks, etc. On the occasions when I do go out with many other people, I usually sit at the back and take in the conversations around me, occasionally chiming in when something important or relevant occurs in the conversation. However, I will admit that if something crops up in conversation that does pique my interest, I'll be centre stage, chewing the fat with the best of them, but that doesn't happen a lot.
It's like the great man said: there are many things I don't like, but what I do like, I love passionately.
Oddly enough, I feel the
least comfortable when alone with some one other person (be it in person or chatting to someone online privately), as the conversations are either one-way-traffic (can be from either party) or full of awkward pregnant pauses. Yet interestingly, this is the only time I can be 100% frank and honest about my own feelings, naturally. Maybe I don't "do" that sort of thing well.
Hmmm... maybe it's my subconscious telling me that I don't really.... belong here?
I don't think 4 statistics is enough to draw any conclusions
But it isn't a case that extraverts belong together at the exclusion of introverts. A combination can find harmony. For example, introverts are often good listeners, while extraverts prefer to be talkative.
I have found that much to be very true, yes.

But then conversations can still end up being very one-sided and unbalanced, and the talkative person may expect more feedback and reaction from the listener, leading to dissatisfaction from the conversation. It's a bit like the "other" form of intercourse, really (but then again everything is

): positive outcomes are more likely if both parties walk away satisfied. [

I can imagine a message board does attract more introverts. It's one of the few ways that introverts can enjoy being part of a large crowd, because they're in full control of what they're reading and what they're expressing.
Also, the message board does provide the large crowd for the extravert to enjoy as well, but it does suffer from being a very filtered way of communicating. We can't see each other, so there is no possibility for body language or facial expressions. No possibility for spontaneous emotional expression, or vocal inflections, as everything we want to express has to be slowly typed in. Extraverts may find that too much of a straight jacket.
The more outwardly expressive people do have other means to express themselves on message boards, be it elaborating in detail about what is on their minds (and cleverly formatting it so that it doesn't exceed the word limit) and using more inventive ways to convey the message, such as describing appropriate examples, linking to external material, posting pictures (when a thousand words need to be cut from their response

) and resorting to colourful metaphors (let's just say).
Given the format of the message board, I see it as more of a level playing field of communication that hampers neither introvert nor extrovert. Yes, it means also that the non-verbal forms of communication are eliminated, but then again the creative extrovert may be able to get around those limitations in a way the introvert might not want to, e.g. posting a picture or a video of themselves.
Although if anything, what might annoy the extrovert is seeing scores of other more introverted people getting their say in more often and more frequently, and often more eloquently than the stereotypical extrovert, but then again that's the nature of the message board in helping people do exactly that by allowing the creation of an online persona of username and avatar and giving them the power to say as much as they want with added confidence and without the social or time pressures, whereas it might not be as compelling in a real life setting.
By the way, I like how this thread has taken a turn away from the humility/arrogance paradigm and shifted towards discussion of personality traits in general. It's an interesting change, although deserving of its own thread, surely...
