The general examples given were of actions: I ask for a hamburger, I am given a giraffe. However, Cuil Theory could be used as a measurement of linguistic continuity, where I say something and I measure the weirdness of your response. This may sound like it is overlapping with what has been already said, but bear with me here.
If I am in a clothing store and state "I am looking for a sweater", there are various responses that I would get that fall within the 0 to -0.999… cuil range. These responses vary from 'Right this way sir' (0 cuils) to 'Here is a fat, hairy man who sweats a lot' (-0.999… cuils).
The reason why I started thinking about this kind of thing in terms of Cuil Theory is because I have two coworkers who constantly break linguistic continuity in my conversations with them. One of them goes towards positive cuils. He will respond to things with complete absurdities.
"I want to eat there for lunch."
"White horse head."
"What the hell?"
"What?"
The other one goes towards negative cuils, hyper-reality, literal meanings. She will respond with statements that could fit, but simply do not.
"You can borrow my pen. But give it back, it's special to me."
"Special? What, do you stick it up your ass?"
"What the hell?"
"What?"
Perhaps Cuil Theory has a place alongside Wittgenstein's language games, and can be a useful tool in measuring how far one has become assimilated into another groups game.
