Yahoo!'s challenge isn't their logo. Yahoo!'s challenge is ensuring their brand becomes associated with whatever they do best.
When I think of Google I think of search, ads, and Android, and GMail. When I think of Microsoft I think of Windows, Office and XBOX. When I think of Apple I think of the iPhone, and the iPad. When I think of Facebook I think of photos and privacy (lack thereof).
When I think of Yahoo there's no defining correlation to anything. I realize many people frequent their services - but personally Yahoo! doesn't stand out as "best" for anything, and I don't even know what direction they intend to pursue to change that perception.
