The place at I used to work used it.
Or at least, tried to. I think there was approximately one fan of Function Point Counting, the general reaction amongst the rest of us was 'You've got to be effing joking?' Still, it was good for a laugh, so long as you didn't actually have to do it. The bit I loved most was the rule that it took as many function points to remove functionality as it did to add it.
So you could effectively do a years work with some well placed deletes :)
On and on and on and on,
and on and on and on goes John.
