An anonymous reader writes: AllThingsD's Kara Swisher reported and tweeted that Marissa Mayer (CEO since July 2012) has just sent an all-hands email ending Yahoo's policy of allowing remote employees. Hundreds of workers have been given the choice: start showing up for work at HQ (which would require relocation in many cases), or resign. (They can forget about Yahoo advice pieces like this). Mayer has also been putting her stamp on Yahoo's new home page, which was rolled out Wednesday. She's also been fixing the customer service 'hold' music. Oh yeah, and she recently gave birth to a baby boy.
