SnappyFingers is a search engine. Not quite like the one that you use daily! It looks for answers in the millions of Q&A's (Questions and Answers) that are spread across multiple sites on the internet on Forum's, FAQs (Frequently Asked Questions), Q&A sites etc.
Why this approach? We discovered that most of the time questions related to a query have already been asked (and answered) somewhere on the net, and a suitable means of retrieving questions and answers related to it was not available
