While I agree that is some worthy snark and I am chuckling, I would point out that for at least the forseeable future it is very likely to be the other way around, due to the fact that young people have worse credit scores (if for no other reason they've had no time to build them up) and Facebook will correlate with younger people for a while yet. (Certainly older people are on there; I said "correlate", not "be solely occupied by".)
