In a press release ("Yahoo! Re-Aligns Organization to More Effectively Focus on Key Customer Segments and Capture Future Growth Opportunities") that could become a classic case study for public relations students, Yahoo has cleared the decks for Susan Decker to become its new COO by firing Dan Rosensweig. You figure a media company such as Yahoo would figure out a more elegant way than issuing a 1,500+ word press release. Of course, Decker's ascension to COO has been the word's worst kept secret so you figure Rosenweig isn't too broken up about getting canned less than three weeks before Christmas. Tom Foremski raises a good point the speculation Rosenveig was the one who leaked the "Peanut Butter Manifesto" a couple weeks ago, while Paul Kedrosky wonders why co-founder David Filo's name is missing from the press release. Yahoo's biggest challenge right now appears to be figuring out what it wants to be. Does it want to be an Internet services companies or a media company? And how long does CEO Terry Semel stick around?
