It looks like Yahoo is set to lose yet another key exec.

David Dickman, whose business cards should read something like Vice President, West Coast Sales, is supposed to leave the position and the company at the end of the month.Dickman isnt part of Yahoos 11person management team, at least, but hes a fairly important person in Yahoos lineup. Dickman worked for Proctor and Gamble, Katz Communications which is a subsidiary of Clear Channel, and Turner Broadcasting before heading to the Internet company. That makes for an impressive resume.
