  The matching of our epoch of existence with the approximate equality of dark
energy and dark matter energy densities is an apparent further fine-tuning,
beyond the already troubling 120 orders of magnitude that separate dark energy
from the Planck scale. In this paper I will argue that the coincidence is not a
fine-tuning problem, but instead an artifact of anthropic selection. Rather
than assuming measurements are equally likely in all epochs, one should insist
that measurements of a quantity be typical amongst all such measurements. As a
consequence, particular observations will reflect the epoch in which they are
most easily made. In the specific case of cosmology, most measurements of dark
energy and dark matter will done during an epoch when large numbers of linear
modes are available to observers, so we should not be surprised at living at
such a time. This is made precise in a particular model for the probability
distribution for r=min(Omega_m/Omega_L,Omega_L/Omega_m), where it is shown that
if p(r) \sim [N(r)]^b (where N(r) is the number of linear modes, and bis some
arbitrary positive power), the probability that r is greater than its observed
value of 0.4, is close to 1. Thus the cosmological coincidence is no longer
problematic.
