I also recommend chash AKA longsufferingly. Her stuff is here (http://www.livejournal.com/tools/memories.bml?user=chash&keyword=Supernatural&filter=all) and here (http://longsufferingly.livejournal.com/856.html#cutid9). I adore her Sam/Dean, but she writes a metric shit ton of J2 as well, and it is refreshingly light-hearted and FUN. When the show isn't taking itself too seriously the fandom usually is, so I really recommend chash AKA longsufferingly because her sense of humor is fucking A+.
