Just when you thought every twist on online coupons was out there, Coupons.com is using Facebook to try to get even more discounts into consumer paws.

The company is launching an app, Brandcaster Social, to make it easier for companies to post scannable coupons with barcodes on Facebook. Brandcaster coupons remain in Facebook, and Brandcaster makes sure potential customers who click on links within Facebook– such as a message in their newsfeed about a friend liking a coupon– to an expired offer see a message offering a perk like advance notice of any upcoming deals. Currently, potential customers clicking on links to outdated online coupons often see a “page expired” message.

Most Silicon Valley luminaries refrain from rants about Silicon Valley. But Sean Parker, who co-founded music service Napster, served as president of Facebook, and invests in music-service Spotify, isn’t a typical Valley luminary– which perhaps is why he felt compelled to paint a bleak, fractious picture of the place to conference goers at Techonomy on Tuesday.

“The conditions in Silicon Valley now resemble the conditions preceding World War One,” he said. “It’s kind of hard to decipher who’s working with whom and who’s at war with whom.”

DreamWorks Animation chief Jeffrey Katzenberg is helping build his movie business by spending about a day a week in Silicon Valley,  and he’s hoping a little Hollywood glitz will rub off on the area’s techheads.

The intiatives DreamWorks is working on– particularly in an ongoing collaboration with Intel– ” will have great application in social media,” he told the audience at the Techonomy conference in Tucson, Ariz. He envisions a future where much social media moves from text-based communication to video- and audio-based, making it more intuitive and instinctual.

The electric cars made by Tesla Motors may be affordable only for the better-heeled, but that doesn’t stop CEO Elon Musk from injecting a common-man touch at his company’s Palo Alto, Calif., headquarters.

The desks, several hundred in one cavernous room, come from Ikea. Just two people have offices– the HR and legal heads. “It comes with heavy responsibilities,” joked Arnnon Geshuri, vice president for human resources, about his tiny office– which with its big window onto the main work floor still is far from private.

Nasdaq’s senior vice president of new listings and capital markets has some bad news for companies looking to hold an initial public offering: don’t expect to ring the opening bell.

The backlog of companies looking to list in the next few months is so big that “I’m going to disappoint a lot of people,” said Robert McCooey during an IPO panel at the Ernst & Young Strategic Growth conference.  “Some people won’t even get a closing bell ceremony.” He counts 210 companies hoping to list on public markets.

Silicon Valley is known for being more fleece than Ferragamo. But former Google executive Sukhinder Singh Cassidy is working on giving the place a makeover via her new shopping site, Joyus.com. Unlike other high-end shopping sites such as Gilt Groupe and Rue La La that are based in the fashion hub of New York, Joyus calls the dress-down Bay Area home.

That means she raises lots of eyebrows with her wardrobe. The picture below, snapped by a friend in the audience and uncropped, shows Singh onstage at tech confab AllThingsD Asia last month with Airbnb CEO Brian Chesky and SurveyMonkey CEO Dave Goldberg. No prize for guessing which shoes are hers.
