On a more serious note, I feel this is the right attitude towards the kinds of things. I've never had a problem with my feed and if something is uninteresting I just block it, period. The feed always ends up being a mirror of the users curiosities and interests so if you have a problem with it it's up to you to change it. Technology is a gateway to knowledge and self actualization, but you can't force those things into people, it's their journey.
I don't believe neither in the existence of introversion or extraversion.
Articles like this reinforce a certain paradigm of behaviour as something inescapable or unchangeable, thus limiting one's ability to explore their environment in more productive ways. I believe it limits one's freedom and one's capacity to change.
Sure, you can take a bunch of people and according to any measure that you create, generate enough statistics that conform to the particular linguistic structure that is behind your hypothesis.
But that doesn't mean that the structure is really there.
If you change either your environment or your perception of it your behaviour will change accordingly. If you reinforce your baseline perceptions and avoid looking at them in a more distant way you will not change your behaviour.
I was very introverted as a child, due to some shattering events in my childhood and always assumed it was a part of me, it was my nature. As time has passed I've changed, not to say that I've become textbook extroverted, but I see my environment differently and I can embrace things in a more productive way. I can move between those definitions of interpersonal behaviour and be aware of what triggers certain patterns that I'm already aware of, and move into mental spaces that I don't feel can be described by this binary classification.
Language, as in your internal narrative, can become either your freedom or your prison. You can choose where you lay down your walls, or if you will lay them down at all.
