[derrida]

I think Sokal's chief criticism of pomo is the misuse of science by some of its representative authors. While Lacan is the only target of his that I've read, it seemed to me at the time that the most important aspect of his invocation of scientific knowledge was its use as metaphor. As Freud and his predecessors drew upon euclidean or mechanistic metaphors, Lacan employs knot topology to reveal more about subjectivity of experience and the creation of the self. Whether or not his math checks out is mostly irrelevant.

The fact that Sokal's books on pomo have probably sold more than the texts he references is understandable- after all, most people would rather the experts do all the heavy thinking for them, rather than risk cognitive dissonance.
