Cuil.com is a new search engine. Apparently some Google ex-employees decided to get together and compete with their former employer. Well, my first response is that it needs a lot of work.
I did a few searches and did indeed come up with some results. Some were relevant. I compared the search "Tired Garden" (with quotes) in Google and Cuil.
In Google, the first site to come up is TiredGarden.info. As a sub page it showed a contest being run. It then lists several Tired Garden entries on social networking sites and some other sites that use the term "Tired Garden" in the page. Without the quotes, the search comes up similar. First is the Tired Garden site and then some social networking sites. Then a few other sited that mention both Tired and Garden on the page.
Cuil did not do so well. First off, I can't tell which is the top entry. This could be a good thing, as it displays 11 on a page in three columns (why not 12, so they are even columns?) meaning that several have top display. The main concern that I have though is that of the 11 on the first page, 6 of them do not show the term "Tired Garden" in the display text. A few of those have the terms tired and garden on them, but not as a single term. Why is WhiteHouse.gov there?
Cuil has this nice thing where they show a picture next to the entry, but where do they get the pictures? I have no idea where the one next to TiredGarden.info comes from. I don't remember putting that picture anywhere on the site.
Cuil has potential, but they are not fixing any of the problems with Google. Overall, they are not worth jumping ship and going away from Google. There are several search engines that are better than Cuil. Yahoo, Dogpile, just about any other search engine I've used is better.
