it's funny, because from an outside adult POV i've been going "goddamn, there's so many kids into homestuck again?", but i can definitely imagine the other perspective, too. without sounding like the elderliest human to ever walk this earth, when i was in high school the trick really was to either con your friends/your fellow art students into reading the comic, or to just wear the t-shirts/draw the characters/whatever until someone noticed.

talking to people about your interests is legitimately just hard to do sometimes, especially when it's niche and infamous like homestuck is, but it does seem like more people are getting into it every day. maybe all you need to do is vouch for it and see if any of your Fellow Art Kids would be down to read it.
