Infinite Jest is David Foster Wallace's gargantuan magnum opus.
Infinite Jest stands out not only because of its exuberant length and DFW's style of writing, but also because a third of it is in endnotes, and the endnotes have footnotes, and anyone who appreciates non-linear writing will have a /lit/gasm.
DFW said in an interview that the structure of the novel resembles a fractal, specifically a Sierpinski Gasket.
Infinite Jest is often the butt of jokes simply for its footnotes and DFW's writing style. However, despite the illusion of difficulty, the book is quite readable, pleasant, and easy to comprehend.
Wallace is also often ridiculed as the hipster Pynchon wannabe. He said he was more inspired by Gaddis and Coover.
