Let's say the spectrum is something like:

  [90s Valley Girl] ... [Richard Dawkins]

(people are one-dimensional in this example)

I'm sure people cluster around ranges on the line. The stereotypical self-obsesed pinhead probably wants more people to reinforce his or her introspection and less talk about the world. They want celebrities, gossip, sales at stores, and shoes, shoes, shoes. The other end of the line probably doesn't want those things.
