We discuss several aspects of the fluidized domain model advanced earlier to explain rotational and translational diffusion rates for fragile glass formers and; in particular; we point out weaknesses in the preceding Comment [Sillescu; Phys. Rev. E 53 ; 2992 (1996)]. Recent experimental results are cited to refine estimates of domain characteristics for orthoterphenyl at T g and to suggest that domain heterogeneity in space and time underlies stretched exponential relaxation behavior for rotational motion. © 1996 The American Physical Society.
