If it's not too late, I would like to nominate this community on LJ. :-)
Encyclopedia of Weirdness is quite possibly one of the best fansites around. Focusing on the TV show Supernatural, the site creator, kentawolf, creates truly wonderful art based on the show and incorperates her own witty (and slightly) sarcastic humor to her masterpieces. This site could have a whole book dedicated to it alone.
