Yahoo doesn't care about the user

That's a pretty simplistic statement, but many former Yahoo staff believe this to be true, and consequently the primary difference between the Yahoo that is treading water and the Google that is surging ahead:

The main problem at Yahoo! is that, long ago, they stopped caring about the user.

They care about Ads, and think that revenue will come from showing more Ads to the user at the same time (more banners) and forget that if they had more users they wouldn't need to put more banners and that more banners means less users.

They care about the development process, creating zillions of internal tools to give a better environment to the developers forgetting that all those tools are already available (most of them for free) and that developers could focus more in delivering good software for their users instead of themselves.
