I hadn't been to one in the US since Anime Expo 6 or 7 years ago. I was happy to discover that a con had been established in my city in the last couple years - something I had always hoped for. The hotel was overrun by teenagers, over half the cosplayers were from Homestuck, and registration was $30 for one day - and it was after 2pm! My friend and I turned around and went for frozen yogurt instead.
Why hasn't the fanbase grown older with the the fans that established it? Why aren't there anime cons for people my age? What is Homestuck? (I'm pretty sure it's not anime.)
