It'd be super interesting to see degrees of separation within particular communities. e.g. I live in a college town with a population of about 65,000, something like 25,000 of those are college students and "don't count" due to their transient nature. As a result, it seems like everyone knows everyone here, despite the 40,000 non-transient population. I'd guess at somewhere around 2 - 2.5 degrees, but it'd be interesting to know the actual.
