I'll start it off.
My current favourite is "The Only City Left'. It has humour and adventure and wonder and horror. The narrator is a young boy with a tone that is at once sardonic and naive, which I get a kick out of. He's just trying to survive in an immense post-apocalyptic ruined city with ghosts and monsters and talking cats. It's a lot of fun! "The Only City Left" updates regularly every Sunday morning.
