Take advantage of Information Cascade by Yelp
Information Cascade happens at every second without people realizing. In lecture, we were given an example that one needs to choose a restaurant between two, and one restaurant is full of customers while the other barely has any. The restaurant is full could be interpreted as the restaurant has a good reputation. While all restaurant tries to create an image of being known, full of customers is not easy to achieve. However, Yelp can help achieve that.
The ratings and comments can be seen as virtual popularity of the restaurant. Good restaurant usually has hundreds of good reviews with nearly perfect rating, and these are equivalent of having the restaurant full of costumers. All these result in a new market — Manipulating online review. If one is willing to pay, he can receive arbitrary number of complements on application like Yelp or push the negative reviews to the back. Hence, the restaurant can take advantage of the information cascade by creating a virtual image that the restaurant is full of costumers.
