Cuil.com is a search engine that provides a never-seen-before search experience. It gives you option to see search in 2 or 3 columns with relevant details. It shows thumbnail size images along with the links, however, their is no option for image search. The search engine backend, depending on the keyword, automatically categorizes the search under various headings.
Despite getting a volcanic start, Cuil is up against the giants like Google, Yahoo, Microsoft and AOL who have successfully maintained their oligopoly over the years. As of now, Cuil has not monetized its services, the way Google does through adwords. Therefore, it needs to be seen how it performs in the long run. The biggest challenege is to have a dedicated pool of users for the advertising campaigns once it launches its ad-displaying services.
