Monday, Google creator Anne Peterson announced the launch of her latest search engine invention: Cuil (pronounced "cool"). Together with husband, Tom Costello and a few other former Google engineers, Peterson has created a search engine to give Google a run for its money.

According to Dan Sullivan, Editor-in-chief of Search Engine Land, the time might be right for someone to really challenge Google, and the best way for Cuil to do this is by capitalizing on key consumer complaints.

So what makes Cuil different and according to Peterson better than Google? There are several key differences. Firstly, Peterson says that she and her team have created an improved search that enables them to search and index a wider breadth of content. In fact, Peterson claims to have over 120 billion pages indexed, and believes that to be three times that of Google's database.
