 What is Si’s full name?
Let Si Get This During a typical lunch time at the Royalton Hotel restaurant in midtown Manhattan, The New Yorker 's Tina Brown might be installed at her usual table, and Vogue 's Anna Wintour might be at her usual table (chewing on her usual meal--a $25 hamburger). S.I. "Si" Newhouse Jr. and his younger brother, Donald, control Advance Publications, one of America's largest privately held companies. It's a closed economy where almost all human needs and desires can be gratified with a miraculous, unlimited currency called the Si. Si spends $20; you save a $1.50 late fee. But Si's generosity extends to even assistants and sub-sub-editors, dining on sushi at their desks.
