Cuil - will it beat google?

Ex employees of Google Inc, have started the a search engine called CUIL claiming it to be the biggest!
Cuil means knowledge in Irish. Well there we go, knowledge aquired by working in Google hehehehe.
My first impression is looks neat, and they have added drill down feature ( which is nothing but search by category). Well that did not immpress me much. I still rate search me more than Cuil, but will have to wait and see who performs better on the long run. But Google is still the king for me
