I didn't know that there was a term for this, so thanks for getting me up to speed. I am also surprised to hear that you consider yourself an introvert, because from (limited) interactions with you so far, I don't really feel that. Perhaps it's the internet and we don't have to be turned on every single second.
I do appreciate how it is though, and I feel the metaphor of the battery works well because I can be very extroverted, but only whilst I have that capacity and it gets burned out quite quickly.
hahahaha yeah, it doesn't show online but IRL, after talking probably about two hours or something, I'd get tired and sleepy. With internet, there's always break in between which is something nice. But even so, making friends is still a challenge because essentially, finding forums or making the first move is difficult for me. Perhaps you're an ambivert somewhere in between? but I think even extroverted person has their limit sometimes.
I feel like I move between extro and intro quite often. Maybe it depends on how much mental energy I have at that particular time, the more I have, the more extroverted I am.
I think the internet has some unexpected consequences in the sense that it is now the norm for people to spend more time away from physical contact. This was already happening before the pandemic, but the lockdowns just accelerated it I feel.
