Generally agree with JakeMorph's take.
I also feel like any reading of Homestuck, especially in terms of how it thinks of it's readers, has to take into consideration the sheer amount of time it was actively updating. I think it'd be impossible to write something for seven years without your feelings and attitudes towards what/how it is supposed to be read changing, especially with the size and voracity of the Homestuck fandom. I personally don't believe Homestuck is supposed to be a spiteful work, and I think it's possible to read it in a positive and constructive way as opposed to pessimistic and destructive.
