We suggest that the slow, scale-invariant coarsening regime in faceting kinetics is governed by long-tailed algebraic distributions of kink-antikink reorganization times. This makes the problem similar to dispersive charge transport in disordered materials. A qualitative explanation is given for the low experimental value of the dynamic exponent describing the growth of groove width.
