If you watch some interviews with DFW and other similar authors, you may come to the conclusion that nobody really knows what they are talking about and it's usually the ego speaking(including Wallaces).
I think that's the point of much of his works:
> Wallace’s great subject was the morass of selfishness, self-rationalization, and intellectualized narcissism into which his cohort of educated, relatively privileged Americans would sink—and were sinking—unless they could find something to love more than they loved themselves.
While the article makes sense to me, there's plenty of filler that detracts from the point. Wallace's work was writing moral fiction for a generation ahead of his time. Many of the themes in his work are more prevalent and pervasive today than they were at the time he wrote them.
