I found this odd little site, and decided I'd make a contribution
Wouldn't your perspective of the universe and other people alter what you think their current cuil level is? An example would be two people watching one of the "a man asks for a hamburger" scenarios come up with different cuil levels, even if only slightly different? And even if they were the same, wouldn't it be irrelevant because they still perceived different views of the events that took place, therefor making the whole cuil system useless? The only way to counteract this would be to somehow unify the cuil system. Unless you do that, the cuil theory is only useful for your own perspective, and would be independent from anyone else's cuil theory; Unless you can unify the cuil theory, you cannot use it to improve a search engine. Since (as far as I believe) you cannot unify the cuil theory, you cannot use it to improve a search engine.
On another note - is this cuil theory in any way related to the search engine except for the fact that "The idea was to lampoon the terrible search engine capabilities of the Cuil search engine"
- do the people who run that search engine even know that this exists? And don't you think that there would be extraordinarily simpler ways of improving the cuil search engine?
