Google, Yahoo, AltaVista, DogPile, all search engines you may have heard of or used. But recently I came upon a different type of search engine, which I thought was rather unique.
At one time you could "Ask Jeeves", but they fired poor Jeeves and now that search engine is just known as "Ask". But now you can ask "Ms. Dewey" and she will try to find the information you request. But be warned, Ms. Dewey can have a bit of an attitude at times and can get impatient if you don't "speak up" and type something so she can show off her searching skills.
Whether or not Ms. Dewey catches on or not is anyone's guess but I think she's pretty cool. The only thing that takes a little getting used to is that the search results appear in a scrolling list to the right of Ms. Dewey, which means you only see a few items at a time.
Pay Ms. Dewey a visit, ask her a few questions, and see what you think of her search abilities.
