I just read a review about BooRah on ReadWriteWeb. I definitely think this is just the beginning of the future of the web. The site aggregates reviews from different sites on the web and serves up results based on semantic analysis and natural language processing - a very cool idea.
It’s interesting how semantic analysis and NLP are becoming hot topics since I was an AI (artificial intelligence) major in college. maybe LISP and Prolog will re-emerge as the next hot web application programming languages.
