A group of ultrarich San Francisco socialites, each with a carbon footprint the size of a small African country, gathered at the home of Larry Ellison's wife Melanie Ellison. The good cause: to promote author Sloan Barnett's book Everything Goes with Green — which just happens to suggest everyone buy her husband Roger Barnett's Shaklee "green" cleaning products. But the conflict of interest wasn't nearly as chatworthy as the conflict of couture!Quelle horreur: Both Barnett and Marissa Mayer, Google's vice president for cupcake-recipe spreadsheets, wore the same blue Oscar de la Renta dress with a green-leaf pattern along the hem! Also, it seems that arm-candy real-estate manager Zack Bogue is trying to tear Valleywag editor Owen Thomas's affections away from stubblicious Flickr developer Cal Henderson by sporting some ursine facial fur. Though my guess is he was just too lazy to shave — that the top button and not the middle button is buttoned on his pinstriped jacket says "sloppy." (Photos by Drew Altizer)

Really, I wasn't trying to be posh for the book party Arianna Huffington threw Saturday for Oxford scholar Jonathan Zittrain and his new book, The Future of the Internet and How to Stop It." I pulled up to Larry Ellison's Pacific Heights manse in a black Town Car because that's the only vehicle I was able to flag down in North Beach. Huffington, the pundit turned blog mogul, greeted me at the door and extracted a promise of my best behavior before allowing me in. (One wonders what these people think my worst behavior might be, and if they realize how tempting living down to their expectations is.)

Stanlee Gatti, the former San Francisco arts commissioner, produced the event, which drew a crowd mixed with the Valley elite, San Francisco politicos, a gaggle of YouTubers, and oddball geek pals of Zittrain. Oh, and some grubby hacks like yours truly. Melanie Ellison, the romance novelist and wife of Oracle CEO Larry, went to high school with Zittrain, it turns out. That's the kind of it's-a-small-world connection the local press corps loves to make a big deal about. But even if Zittrain didn't have this chance connection to the Valley's movers and shakers, I'd think he'd be drawing attention from its inner circle anyway.
