The official unofficial Karkat Goes to a Convention thread

Karkat Goes to a Convention is my favourite fan-adventure. It drew me into MSPFA after I read Homestuck, and so is basically responsible for introducing me to all of my online friends. It's also just a great story about Homestuck, about fandom, about art, and about Karkat going to a convention. So I thought I'd create a thread where we could talk about it, if we so desire!
