Yahoo Local vs Yahoo Pages?

Since Yahoo moving from it's "Yellow Pages" to "Yahoo Local" . . I find it increasingly difficult to locate business via this vehicle. In other words . . If I type in Auto Parts in the window along with the city . . I get almost no representation from that category, but I get all kinds of unrelated businesses to sift through. It's to the point where I must know the very business name I'm looking for, type it in my browser and go on their website or pick it up through a different party review board. Why did Yahoo move away from the Yellow Page service? Yahoo Local is really not a particularly good service, especially when you can't find what you're looking for, and also because Yahoo has permitted unbridled spam on the User's Review boards. Is Yahoo ever going to get back to Yellow Pages, or do I just need to dismiss this feature and move on to something that works?
