Just about everybody seems to be on Facebook these days: students, slackers, presidential candidates - and billionaire captains of industry. The Silicon Valley gossip website Valleywag has got its hands on the Facebook profile of Microsoft's chief executive Steve Ballmer, which is only supposed to be visible to his on-line "friends".
Ballmer, who is the 31st richest person in the world, has posted a fetching picture of himself playing golf. The page reveals that he's just been for a weekend at a log cabin. He has also found the time to poll his on-line friends (of whom 85 are his employees) with the question: "Boxers or briefs?"
I'm not sure whether this is endearing, or disturbing behaviour from a 51-year-old father of three.
