I just read jailbreak and bardquest and I'm about to read problemsleuth (I never finished it the first time) it seems like hussie took elements from each thing and used it to build up the next and next thing, and yet each is so far removed from the other that it's almost absurd to see them share the same website. Theoretically, do you think a comic after homestuck would "build" on it and be exponentially bigger and more complex?

There’s a few things your analysis doesn’t touch upon! Not only did Hussie build from previous experiences and improve on the art style and refine little elements, he also changed how the comic itself was being delivered. Jailbreak was an anything-goes sort of deal with Bard Quest being his attempt at making a branching adventure. Both of these were all decided by user input.

Problem Sleuth is where things start to get more complex, where Hussie presented a simple setting like in Jailbreak, and let it run for a lot longer than Jailbreak- The fact that made him realize that, unless he took the reins of the story, it would just keep on expanding. Towards the end of Problem Sleuth, Hussie began to cherry-pick commands that’d advance the plot or even outright made them up.

Homestuck came from that very same concept, allowing user input and interaction with the fans, but leading it all down a predetermined path, a story he’s got the outline of in his head. Which got even more complex once he had a solid idea of where he wanted the story to go, and reduced the user input to a minimum. It’s possible Hussie’s next story will be that, a story, with no direct user Input, planned meticulously from the beginning. Whether that makes it more or less complex, though, who knows. I mean, it’s Hussie. He has crazy ideas and mixes stuff from just about any possible and existing literary piece and medium he likes and knows about, it’s still going to be a complex-ass story.

The question is not how the next story will be, but on WHAT it will be. Will it be another Webcomic? Or something else? Maybe now that he’s built fans and friends and has got some deals with Viz, we will literally see an Anime directed by Hussie.
