The question then remains whether "ln(W)" is an information-theoretic quantity. If it is measured in bits, one can say that, given the macrostate, it represents the average of the minimum number of yes/no questions one must ask to determine the microstate, clearly an information-theoretic concept. Objectors point out that such a process is purely conceptual, and has nothing to do with the measurement of entropy. Then again, the whole of statistical mechanics is purely conceptual, serving only to provide an explanation of the "pure" science of thermodynamics.
