ReadWriteWeb brought my attention to restaurant review aggregator BooRah.
What sets the service apart from other community evaluation sites is their use of semantic and natural language processing to analyze whether a published review is positive or negative ("rah" vs. "boo").
As RWW notes, among its handy features are direct links to key terms inside reviews. For now, finding "good are in Brooklyn" is not all that helpful, but with refinement it will be a useful tool.
BooRah is among a growing contingent of sites on its way to creating a more intuitive and easily navigable web.
