I’m about halfway through Infite Jest, and enjoying it.  That wasn’t always the case.  The first three hundred pages were a struggle.  Perhaps, that’s untrue.  There were highlights, moments when I laughed, followed by passages when I was unsure how this section related or who the characters were.  In the past six weeks I haven’t had much time to read the novel.  When travelling, it’s not very convenient to lug around 900+ pages of prose with another 50 pages of endnotes.
I’ve also been trying to get my friends and family to read the book.  Besides Wallace’s love for language, the book is funny.  My best attempt to describe it has been to say that it touches on tennis, addiction, entertainment, politics, and absurdism.  How those come together, you have to read for yourself.
