Editor Lee Montgomery opines that these writerly pieces behave like "intimate conversations," which is one of the reasons it makes some kind of sense to offer these to the general reader.

As importantly, almost any subject is good reading in the hands of a talented writer. And believe me--though these are not household names (which writers are?)--these are fine writers.
