While accusing Yahoo News GM Amy Iorio of tiresome nepotism, our last tipster said Iorio's sister, Denise Iorio "has no clearly defined job function and doesn't work on any distinct property." Seems Yahoo caught on. Denise Iorio caught the sharp end of the ax yesterday, a tipster tells us. Friends and neighbors, that means you shouldn't believe her when she says she's on an extended maternity leave.
