I stopped reading Homestuck after a short while, so what's wrong with John/Karkat essentially? I keep seeing wank about it with no explanation.

Yeah, I loooove Tumblr but it seems to be biased for artists over writers, and conversations are hard to hold on there like on LJ. So I'll never move over there 100% because I really do need a site for actual convos and fics and stuff. But I'm there (lannistersroar)!
