this particular tirade of karkat’s seems a particularly egregious hint that Homestuck’s author is dead and that the task of interpreting it lies in the hands of the reader.
in fact if I didn’t know better, I might say that those last two lines are telling us: “given the online new-media nature of Homestuck, I, the author, am also here to interact with you, the reader, and provide further information about my work, thus subverting the entire concept of death of the author itself by allowing the author’s own words to influence interpretation of the text”
