Yahoo's local search beta launched today. Chris Sherman has a detailed review.
One interesting feature that Chris underemphasized is user ratings. From Yahoo's press release, "Users can now rate and review almost every business in the country - from dry cleaners and dentists to florists and fine dining establishments."
Very cool and very useful. Not only does it provide a differentiator with business directories like the Yellow Pages, but also Yahoo is now offering a service much like what guidebooks provide. Citysearch, Zagat, Travelocity, Fodor's, and many others should be concerned about this new development.
