Scratch another name off ex-Yahoo Bradley Horowitz's list of Yahoo's doomed and departed. Yahoo exec Jeff Weiner, the man in charge of core products like Yahoo.com, Yahoo Mail and Yahoo Messenger has resigned from the company, a person familiar with the situation told the LA Times. He's accepted a new role as an entrepreneur-in-residence shared between venture capital firms Accel Partners and Greylock Partners. That means he'll get an office (or two), a big paycheck (or two) and a charge to think up big ideas — a great gig for a new dad. It's an unusual arrangement, but both firms are stuffed full of ex-Yahoos who probably see an angle in helping Weiner out. The LA Times's source says Yahoo will not immediately replace Weiner, but instead delegate his responsibilites to group of execs. Kind of the way you spread peanut butter over toast, you know?
