If there’s a new dawn in the age of search, Datafiniti is the sun. They are the first to take a new and profound approach to search in years. Most search engines return a list of links to web pages, but Datafiniti has much bigger plans. Instead of links, they return a set of data. A search for a burrito in Texas would give you a list of restaurants complete with goodies like reviews in addition to the important bits like name and address. The dataset itself has been out there for years, but its the aggregartion and presentation that’s different. With the Datafiniti API, it is now possible for developers to easily integrate that data into web applications.
