Did you hear about Vadlo? Nice search engine for scientists. Better than Scirus.

Cuil has a better chance of winning the public’s heart. They launched under a great deal of pressure and misconception. It took Google about 2 years to reach the status of “major search engine”.
Wikia is really no better than a directory with an odd interface. At least Cuil is willing to crawl the Web and its search results ARE relevant (a refreshing change from Google’s irrelevant bias toward link-rich sites).
Cuil also has the better user interface. They just need to stay the course, add robust features, and improve their freshness.
