I've added a ChaCha Search Engine to my blog. If you have always used Google or Yahoo to search you may find ChaCha a little different. With ChaCha you can search alone or with a Guide. Interactive searching with the Guide or maybe you are busy and while you are working on something you can have your guide searching for something else you need to finish whatever you may be working on.
If you've used it before or you try it now, let me know what you think?
