Each week, paper presenters will be posting a thread to Piazza for their reading. Every student must comment on each reading (except any they are presenting) by Tuesday at midnight. This includes discussion leaders. Comments should be substantial (i.e., at least a paragraph) and raise something interesting you found about the article, constructive criticism, related work, etc. You are welcome to either discuss a new topic within the article’s post or reply to a classmate and continue the conversation thread. These pre-class comments will be used by the discussion leaders to guide discussion. Discussion leaders: be sure to read your classmates’ comments before class. Late comments will not be counted for credit. Partial credit will not be awarded.
