Comment on: ``Nonextensivity: from low-dimensional maps to Hamiltonian   systems'' by Tsallis et al
  The critique against using Boltzmann's microcanonical entropy, an "ensemble measure", as foundation of statistics is rebuffed. The confusion of the microcanonical distribution with the exponential Boltzmann-Gibbs (``BG'') distribution is pointed out. Boltzmann's principle is clearly superior over any Tsallis q-statistics in describing the equilibrium of small systems like nuclei and even self-gravitating systems as paradigm of non-extensive Hamiltonian systems.
