The wiki on him is:
Wallace used many forms of irony, focusing on individuals' continued longing for earnest, unself-conscious experience, and communication in a media-saturated society. Wallace's novels often combine various writing modes or voices, and incorporate jargon and vocabulary (sometimes invented) from a wide variety of fields. His writing featured self-generated abbreviations and acronyms, long multi-clause sentences, and a notable use of explanatory footnotes and endnotes—often nearly as expansive as the text proper.Ah, acronyms, explanatory footnotes, jargon.... Now it makes sense. Still better than the one outlier result: Isaac Asimov. I really do not want my next book to read like science fiction.
