Author Ben Mezrich.So Mr. Mezrich had to do some guesswork about Mr. Zuckerberg. And guesswork — long, lyrical, hash-slinging, protracted feats of guesswork, based only glancingly on the rare incontrovertible detail, like the fact that Mr. Zuckerberg liked to wear flip-flops in college — is Mr. Mezrich’s specialty. It served him lucratively, if not well, in “Bringing Down the House,” the book that became the basis for the film “21” (another story of smart college kids striking it rich in the real world, in that case in Las Vegas casinos). It should not go unnoticed that Mr. Mezrich started out as a writer of science fiction.
In “The Accidental Billionaires” he so enthusiastically favors hot air over specifics that he waits until the end of the book to offer up three little words that speak volumes about Mr. Zuckerberg’s Sphinx-like persona. However shy, vague, withdrawn, affectless and computerlike Mr. Zuckerberg is said by this book to be, he turns out to have business cards that say “I’m CEO — Bitch.” That phrase outweighs all 258 pages of Mr. Mezrich’s stalling. (The last two pages of this 260-page book are devoted to a list of published sources. Mr. Mezrich relied heavily on The Harvard Crimson.)
