Widgetmaker RockYou raised $35 million from venture firm Doll Capital Management and private investors. Rumor has the deal setting RockYou's value near $400 million. RockYou created Facebook widgets SuperWall, Vampires, Likeness, X Me and claims 87.5 million visitors a month and 2.7 billion pageviews. Paying advertisers on RockYou include Paramount, New Line Cinema, Sony, Microsoft, and CBS. But they're not paying much.

The longevity of troubled tech publisher Red Herring was a mystery until one ex-employee enlightened me: Publisher Alex Vieux simply doesn't pay his bills. What a brilliant way to achieve positive cash flow! Alas, Vieux has encountered a creditor who won't be stiffed: the IRS. The agency is looking into Vieux's Herring for what may be $2 million in unpaid payroll taxes, ex-employees who have been contacted by investigators have told me. Vieux is experienced at dodging the taxman: Farley Duvall, a longtime lieutenant, told colleagues he'd fled French police seeking to seize company documents in Paris, and drove in the middle of the night to Switzerland, where he rebuilt the Herring's European operations. Now Swiss authorities are asking questions about — you guessed it — unpaid taxes. But it's the American taxman who may put Vieux behind bars.
