"If one is fond of folk music, he should try the Mudcat."It seems no other Americans learned to say, "If one is fond of folk music, one should try the Mudcat." One might feel it is more consistent to use pronouns that agree.
This string is extraordinary. Isn't it amazing how the word "grammar" attracted so many people who are passionate about language? You are all quite amazing and wonderful. I'm glad to have found Mudcat again.
