Abstract
In the era of precision cosmology the Virgo cluster takes on a new role in the cosmic distance scale. Its traditional role of testing the consistency of secondary distance indicators is replaced by an ensemble of distance measurements within the Local Supercluster united by a velocity field model obtained from redshift survey based reconstruction. WMAP leads us to see the Hubble Constant as one of six parameters in a standard model of cosmology with considerable covariance between parameters. Independent experiments, such as WMAP and the HST Key Project (and their successors) constrain these parameters.
