AIUI, Strassen gets used moderately commonly with non-floating-point datatypes, where numerical stability is less of a concern and multiplications are more useful to minimize than memory traffic. But from what I can tell, every floating-point BLAS library eschews Strassen, despite a steady trickle of papers saying "hey, there might be some small wins if we go to Strassen!"
