Find an Answer with Answers.com
Thursday January 15, 2009
Answers.com is an innovative way to find answers on the Web, without searching for them. Instead of going to your favorite search engine and typing in a query, then sorting through various links to find the answer that you are looking for, Answers.com "displays quick, snapshot answers with concise, reliable information." Find out more about Answers.com. 

I’ve been using their wiki answers service for a while and it’s pretty cool. For quick answers I also find ask.com works really well.
I use answer.com with toolbar at http://www.absolutetoolbar.com
it automatically opens new page with answer.com for a selected word.
