eBay Marketplaces is a core property of its parent company, encompassing eBay itself, Kijiji, Shopping.com, and StubHub, among other sites. Unfortunately for eBay, the unit may soon be without a leader, as president Lorrie Norrington is resigning. eBay critics shouldn't draw too many conclusions about the cause of Norrington's departure, as it's rumored to be due to an illness in the family. It's more the aftereffects that could be problematic.
