justas wewelcomeproper pun ctua tion,
But if you're thinking professor Kosko is the first author to do away with commas, apparantly there was also some guy in Dublin named James Joyce, who wrote many long passages in Ulysses without them. (Of course, Samuel Beckett, E. M. Forster and Somerset Maugham made up for the dearth by using commas instead of periods!)
I think the best book on the subject is Lynne Truss's Eats, Shoots & Leaves, which not only makes the proper use of punctuation fun (honestly!), but also explores the history of punctuation and reminds us of other Joycian quirks like George Orwell shunning the semicolon. Of course, he had no idea what he was missing ";-)"
