Last I wrote to him (2 years ago) he was still at Rutgers (RUCCS). I am not sure how much worse he has become considering Psychosemantics (from a few years ago) was about as much hard work as this one is! I have not read his Massive Modularity book.
Quine has such interesting and timely (for his time, but perhaps now too) things to say that his style is unfortunate, especially given that he follows in the tradition of the mathematician turned philosopher Bertrand Russell. In that tradition, Putnam (with and w/o Benacerraf) seems more readable and less annoying, though I am not sure I agree with him (FWIW).
