My search engine of choice is Google. Occasionally I use one of the other popular ones. Now another one comes along claiming to be the world’s biggest search engine. They say they have already indexed over 120 billion web pages. I see that some of the technical articles are critical of CUIL (pronounced COOL). My approach to this sort of thing is to try it for yourself and see if it provides good results. I can’t say that I am immediately attracted to Cuil, but it will probably improve. When I entered my name [isn’t that what you do?] a lot of the posts on this blog came up.
Cuil is an old Irish word for knowledge. For knowledge, ask Cuil.
