I think there are genuinely lots of 4's and 5's on the internet. First of all, it's an introverted place to be. For fours, a site like this can be a place to indulge in the brokenness and figure out their own uniqueness. While in reality, they can just be the dumb emo person who doesn't get a whole lot done, crying on their diary and burning their wrist with cigarettes. They can find people "who understand them" online. Fives have tons and tons of benefit to using the internet. "Knowledge seekers." There is lots of knowledge to be had online. IRL, on the outside, unless they are the "mysterious and brooding" actor or playwright type, they may just come off as plain and boring. That being said, everyone else has their reasons for using the web. Ranging from productivity to introversion to loneliness and boredom. I think there's certain types of people who are naturally going to spend time there. You wouldn't find a five gaining as much from being at a church supper. (Not saying it doesn't happen, I'm just saying it's less likely.)
Rambling aside:
To me,
coolest type: 3. I just respect their ambition and ability to act on their desires and get things moving. (I know their desires aren't always 'truly' their desires and could just be putting on a show, however they have a quality that I would love to possess naturally.)
Worst type: 9. I like hanging out with them and talking to them in reality. But I wouldn't want to be known as one primarily since they don't appear to have as strong of an identity according to type descriptions. It's the only type I would have an aversion to adopting for myself. Since sixes are really common, and "unique and different" is more desired around these parts, 6 could be viewed as lame too. I think they have a lot to them, there are just so many of them. Nobody here wants to be part of a "herd."
But that's circular thinking. Do we not want to be part of a herd so we're fours? Or are we fours so we don't want to be part of a herd?
