Yeah, my whole thought was, if I wanted to play someone who was mad all the time, I'd play Karkat.

You want a Homestuck, huh? The cast is pretty big right now, but we're a welcoming group! I personally would love to see a Bro in the mix, but then I'm biased towards all things Strider. I personally take the approach of going "hey, this guy is cool, why don't I slap an app together and see what happens!" Like, literally. I did that with both Equius and Signless.
