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.2 pages, no figureStatistical MechanicsNuclear TheoryAtomic and Molecular Clusterstext
