> This article also doesn’t do justice to the nuance that introverts find interactions with other “draining” … but it’s not necessary that they suck at it.

The nuance on the flip side that I see discussed even less is that extroverts are not necessarily actually good at interacting with people, especially in more structured settings, they just maybe enjoy doing it more. Presumably there is at least some correlation between extroversion and good social skills, since if nothing else the extrovert might get more practice. But my anecdotal experience is that they're definitely clearly distinct personality aspects that fairly often do not go together.
