I've received some really wonderful, clever feedback in the last few days, so this question is well-timed! I really appreciate all feedback, and kudos, but I especially love it when I get a comment that shows the reader has really engaged with the fic -- that it's made them think, or have an emotional response. I value that a lot.

(I missed last week's question, but ironically, the same wonderful reader of the last few days ALSO left some feedback that bugged me -- "Cool motive, still murder." I mean, yes, but I worked hard on that motive, dammit! IT WAS A GOOD MOTIVE (for murder).
