This is a .NET instant answer library written in C# for the DuckDuckGo Instant Answer API. It was created by Tim Kelly. DuckDuckGo is a search engine that aims to protect the privacy of users who enter personal queries. It does not track users' behavior. DuckDuckGo's RESTful API displays responses in JSON and XML.
During the past four months we've seen not one but two well known real-time search engines disappear. First there was OneRiot, which in October 2010 decided to focus on advertising. More recently, Collecta closed it's real-time search engine and API to focus on alternative real-time products. Digging further into real-time search offerings you will also discover that crowdeye has also decided to pull its real-time search engine. This now appears to leave Topsy, and of course Google as the main players focusing on building a real-time search destination. Does this trend signal the end for all real-time search engines or just that their focus has been wrong?
