Hi, I will do a mashup with Amazon Advertising API, think it like Hipmunk a user friendly search web app. It will have a map will show popular search from regions etc and a visual search help. What kind of features would you like to see? What kind of other services would you like to be integrated? For example wiki links, Twitter mentions...<p>*I had posted same question on Quora:
