In my experience, beginners tend to underabstract, and it's the intermediately-experienced ones that go too far in the other direction. The most experienced ones are somewhere in the middle and closer to using abstractions where they make sense. Unfortunately, the majority of the community and industry is in the middle group.
"the majority of the community and industry is in the middle group"
I.e., "intermediately-experienced" and younger than the "most experienced". As I said. You are unlikely to find yourself relying on a library written by a beginner.
Yep, my experience as well. I'd say (in keeping with the article's terms) that the intermediately-experienced tend to overuse indirection, but underuse abstraction.
