This is one of those articles that kinda holds itself up by only a gimmick, which is increasingly annoying to use as the document continues on. The footnotes themselves don't really have much in them, besides one joke about the blackboxes (which admittedly made me laugh, and I wish there were more of them)
Speaking of which, I wish there was just more in general. As it is, it just feels short because it can be. There's nothing really important about it, and I just can't get myself into it. I'd really recommend using BetterFootnotes for reader's sake but I think there's just not enough for me to get into it.
EDIT: After giving it another read, I think I could get myself into the shorter format if there was just some more extension into the Discovery, and if the article's gimmick was just easier to use in general.
