While Conde Nast mourns the loss of Jane and Bauer buries the fetus of Cocktail Weekly, Hearst is stumbling through some problems of its own.

Atoosa Rubenstein's replacement at Seventeen may not be faring too well, indicates a well-placed Hearst source. Since Ann Shoket took over in January, as we first reported, she's watched as editor after editor has walked out the door while, as one tattler notes, she's "turned Seventeen into CosmoGIRL! Lite, packed with celebs, cartoonish layouts and fluff."

You can see where this is headed.

Not that we're keeping track or anything, but:

• Ying Chu, beauty director, jumped ship to Marie Claire in May, barely a year after starting at Seventeen, and after four months of working with Shoket.

• A few months before that, Jillian Mackenzie, the executive editor, "literally ran back to Allure" after being at Seventeen for five months.

• Andrea Rosengarten, executive managing editor, lasted just four months.

• Ann's assistant, Claire Windsor, quit after six months.

• Melissa Daly, the health/fitness/relationships editor, left the magazine two weeks ago after eight months (after working with Ann for 5 months).

• And at least five other editors have quit since Ann took over.

Seventeen's explanation? "As you know, when a new editor comes on board, it’s pretty typical to see staff changes," Hearst spokeswoman Letena Lindsay tells us. "Seventeen is no exception. Some have chosen to leave, and some have been let go."

So what's in store for Yesenia Almonte, the new beauty director who came over from Latina and started one week ago? With editors describing Ann as "indecisive," "inconsistent" and "in WAY over her head," we've got a feeling.

Meanwhile, if you'll recall, Seventeen's ad pages are also falling, though Seventeen's camp would like to mention that Ann's "first issue – April 2007 featuring Avril Lavigne – had a 17 percent newsstand increase over last year’s April issue. Seventeen continues to have the largest circulation across the teen category." Noted.

Some might point to Ann's reliance on CosmoGIRL!'s approach, as "that's all she knows," says a source. "If she wants to explain how a layout should look, she'll pick up an old issue of CosmoGIRL!. If she wants a story structured a certain way, she'll refer to a story in an old CosmoGIRL!. … Ann has no new ideas."

Retorts Seventeen: "It would, however, be a mistake for Ann not to bring her 10 years of teen experience to this job (particularly from such an amazing sister brand as CosmoGirl!), as would any editor…that’s how she became an Editor in Chief!"

But wait. Isn't that also how ELLEgirl's Brandon Holley ended up atop Jane? And then, well.
