I find it interesting that while there's only really one way to view the main text, there are multiple ways of dealing with the comments, either as sidebars to the main text, or as pages all by themselves organizable by time posted or card (added this past June). It feels to me like an attempt to add legitimacy to the comments, or perhaps make them seem more important or intergral to the work than they actually are. Because a lot of the comments don't feel particularly useful to the reading of the text, and seemed to really taper off once people adjusted to the format of the primary text.
