Fresh off his tour of mainland China, Facebook CEO Mark Zuckerberg celebrated the New Year in Taiwan. Above, Zuckerberg and his girlfriend stroll through Taipei's famous Snake Alley market on Thursday. He even stopped for a picture with a fan.

Barry Diller—a man who seemed positioned to reign opulently over his IAC media empire for years to come—announced this morning that he's stepping down as CEO of IAC.

Credit where it's due: Barry Diller knows how to vacation. The IAC boss is tightfisted at headquarters, but his holidays are plenty decadent. There's the corporate jet; the giant boat; tropical beaches; and a set of young blonde twins.

What does one insanely rich tech guy give another insanely rich tech guy as a wedding present? If you're a Google founder, the answer is reportedly "a party jet."

A former Washington Post reporter is said to writing a comprehensive profile of Mark Zuckerberg. Comprehensive enough, maybe, to include the old romantic entanglement Zuckerberg just fibbed about. Prepare to do a little more sweating, Mark.

Internet empress Arianna Huffington is in Amalfi, Italy, apparently, mixing it up with Newt and Callista Gingrich, mega-entertainment lawyer Allen Grubman and his wife Deborah, and Barbara Walters. Proof fancy yacht vacations really are out of fashion for the super-rich?

Blues music is built on shattered dreams and broken hearts. This is why someone must make Cablevision CEO Jimmy Dolan happy ASAP. It's the only way he'll stop recording terrible vanity blues albums!

The new status symbol for hedge funders and corporate tycoons: feminine bracelets worn on their wrists next to their expensive watches. It's an "I'm so insanely rich, I get to break the rules" kinda thing, apparently.

IAC CEO Barry Diller expensed $1.6 million in personal travel in 2009. ($4,600/day!) That doesn't include business trips—just vacations. Welcome to MogulAir. Would you like a blanket and a pillow made out of diamonds? [NYP]
