Rumor has it Scott Gatz, the brain behind Yahoo's search strategy earlier in the decade, more recently heading up part of Bradley Horowitz's Advanced Products Group, will leave Yahoo at the end of the year. Our source, who claims to have failed in trying to hire away Gatz in the past, tells us Gatz always professed to be happy at Yahoo. Apparently that's changed. Why?

Gatz has been mum. But likely as not, Gatz may have gotten sick of working withSalim Ismail, the publicity-hungry Silicon Valley Tool charged with Brickhouse, the sexier part of Horowitz's innovation empire. Either that, or Gatz is just eager to spend more time nerdspotting for Valleywag. Scott, we have an opening for a party correspondent, if you haven't heard.
