If only Yahoo would listen to Kara Swisher, she might stop emailing me"Yahoo striking a Microsoft search deal first makes more sense" than closing a merger with AOL, writes overproductive BoomTown blogger Kara Swisher. Tracking the complicated, self-conflicting relationships between Yahoo, AOL, Microsoft and Google is like trying to read Prince Valiant without a cheat sheet. Swisher's latest megapost fills in more details, but doesn't lead to anything more definite than "both Yahoo and AOL have to get to the core of what they are and are going to be." Ah, more layoffs.
