I watch this show pretty religiously. My interaction with fandom is generally passive, though. I read fic and spoiler boards, but don't participate in discussion, meta, or shipping because I have found that, by and large, the fans are a rather unpleasant lot. From what I can tell, if you can find the corner of fandom populated by those who agree with you on shipping and character preference you can have fun, but I tend to find the near-constant wanking and generally negative and nasty attitudes to be off-putting.
