>>83464968Hussie had three qualities that made Homestuck work. Everything else was incidental.
1. Insane update schedule. This is not the only ingredient, but it is the MOST IMPORTANT ingredient to Homestuck. It was what propelled all other aspects. The speed of updates turned it into a phenomena that caught us all in the torrent. When this left the comic after Mom and Dad died, around that time, is when the comic died.
2. Color. Hussie was really great at simple, striking, bold colors and lines and using google images to integrate into his scenes. Everything had a vibrancy and game-feel to it that he nailed. This got more sloppy, lifeless, and haphazard over time.
3. As you said, he attracted talent. He also had us, the readers. Overexpanding his team, and closing reader suggestions killed the comic as well, because then it was all on him, and his ego could not handle it or the uncontrolled scope.
Hussie authored his own demise.
