I know the whole "name the characters as they appear" shtick is, at least early in homestuck, more of a genuine audience input springboard than anything else, but it does kind of tie in nicely with a lot of the really meta stuff the story gets into later on.
Like, their god tier titles are their Roles within the myths they're living out. In the epilogues they fade into meaningless chaos once they're no longer tied to "canon." Everything about them is tied to the story and tied to the advent of sburb, so they can't truly be named until the day that the game and the story both start.
