Having escaped John Malone's hook, former studio boss and internet tycoon Barry Diller is attempting to reinvent himself, says Portfolio's Duff McDonald. The new Diller trademark? Humility. "We were kidding ourselves if we thought we could pull off an integrated conglomerate that acts like G.E. or P&G in anything less than 10, 20, or 30 years." Diller is indeed cutting internet conglomerate IAC down to a more manageable rump of web sites such as Ask, Citysearch and Evite. But the 65-year-old tycoon hasn't entirely lost his trademark vindictiveness. Doug Lebda-who sold Diller online mortgage search engine Lending Tree for $726m before the real-estate bubble burst-was prepared to buy the business back at a discount. Why hasn't that happened? "No one is allowed to school Diller twice," says a mogul watcher.
