What should I call a person writing/adding comments (by pressing "add comment" link)? Commenter or commentator?
From a deleted answer, I understand that there are commentators (like those unilaterally commentating or closing questions) and commenters (those entering in discussion with others). Is it correct?
Isn't commenting by answering/questioning another commenter/answerer/questioner a live event? And what is the difference in these definitions between a commentator and an answerer?
