I am so turned off when a post will be about Character A, and then right at the end, the OP will slip in a dig about Character B (or pairing A and bashing pairing B). It has nothing to do with the rest of the post. I just want someone to write meta or squee about a character on his or her own without it being at the expense of another character. It always leaves me feeling a little less love for the original Character (or pairing) A.
