It seems like sort of a back water but as I recall, they had some interesting stuff. I feel like there was a "learn" command and another one that tried to tell you about common grammer (english, not yacc) problems in your prose. So far as I know, those didn't make it into the mainstream, or if they did, they were weak reimplementations that didn't work as well as the originals.
