I personally would say no to any type of like, helpful, not helpful and etc button but if there is going to be a "like", "helpful" or other button du jour, I would say no to any type of "negative" (i.e. not helpful) button as all that will do is tick off the poster who made the comment and if a post is truly not helpful and along the lines where it needs to be moderated, then that's what the Report Bad Post button is for.
