Right, but the idea here is that you shouldn't be allowed to comment until you've at least apprised yourself of the subject.

Of course, hiding a button with JavaScript is trivially defeated by your typical HN user, but I want to assume at least to some degree of good faith... this would be more of a "commitment device" than anything.
