First, former Yahoo CEO Terry Semel banned Rachel Glaser from the corporate jet. Now the annoyingly loud talker is out of the corporation. The senior vice president will leave the company in 2008, reports Kara Swisher, who's an expert on loudness. On her way out the door, Glaser could hold it open for VP of media engineering Bharath Kadaba, also soon to depart. A source told Swisher that Yahoo is just trying to cull its executive herd. Not a bad idea, considering that as recently as September, that pack included 300 vice presidents and several dozen senior VPs. But there's likely more to Glaser's departure, at least, than simple economics.

Mark Rubash, the Yahoo finance executive who recently left the troubled Web giant — this, despite having the favor of new president Sue Decker — emailed Valleywag to deny that he lost a turf war with Rachel Glaser. If anything, he won the turf war, he says, getting offered a job in which he would have overseen Glaser's group. Instead, he turned down the job and left altogether. He's now CFO at Rearden Commerce, a startup in Foster City. In his note, though, he leaves a tantalizing hint about Glaser.

We hear that Mark Rubash, left, a Yahoo finance executive hired by Yahoo president Sue Decker in February, is already leaving the company. Rubash, a favorite of Decker, was apparently the loser in a turf war with fellow finance executive Rachel Glaser, pictured here to his right.. We can't help but wonder if Glaser, a commuter from Los Angeles who's widely disliked on the Sunnyvale campus, will last much longer, as Yahoo undergoes a top-to-bottom reorganization. "She has no financial acumen," whispers one tipster — a fact that, if true, can't be lost on Decker and her recently hired ally, CFO Blake Jorgensen. Update: Rubash says he was offered a job over Glaser's head, but turned it down.
