It looks as if Yahoo! will be undergoing a reorganization effort in the future. Both Matt Cutts and Greg Linden provide some interesting commentary, and there's plenty of other news on the subject.
I am not an expert on the search industry, but it seems to me that this was the only way for Yahoo to stay alive. If their recent TV listings overhaul is any sign of their current state of affairs, then I am ready to declare the company in shambles. The old TV listings page was light weight and usable; the new one is bloated, confusing, and very ugly. Although their primary competition (Google) doesn't have a TV listing service, I can assure you that if they did, it would be light weight and responsive. Google knows what users want; Yahoo appears to only know what they want for their users. That kind of direction can only lead to collapse. Hopefully Yahoo can turn things around. As much as I love Google, we need some semblance of competition.
