It's interesting. It's a metasearch engine that hits a series of specialized databases to try to answer your question. From their about page:
- We've collected authoritative facts in Answers.com by licensing top-quality reference work to give you concise, relevant information on each of over a million topics. We handpicked reference from publishers such as Houghton Mifflin, Columbia University Press, Merriam Webster, Computer Desktop Encyclopedia, Inlumen, Investopedia and Who2 (just to name a few)...
Try some searches on it. For example, ask Answers.com, "What is a blog?" "What is a tsunami?" "Who is Jeff Bezos?"
At a time when some are talking about how big they can make their search index, it's interesting to see the opposite approach, focusing on a few, specialized, high quality data sources. Sometimes less is more.
Update: Apparently, Google is experimenting with using Answers.com instead of Dictionary.com for word definitions.
Update: Google has switched over to Answers.com for all word definitions.
Update: Walter Mossberg at the WSJ has an interesting and well-written review of Answers.com.
- Answers.com is ... a start toward a new search paradigm where the object is to provide real instant information, not just links to pages where that information may, or may not, be found.
