Hi Steve,
I'm not sure how you are counting now, but I recall that many of your feedback remarks begin with a summary of how many were for/against or how many liked/disliked. I know it may sound kind of "Netflix-y" but one thing that might help make the feedback more efficient is a rating system. At least that way, you would only have to read the posts to get your favorite comment or the one that sums up the general feeling. Certainly those who appreciate the amount of work you put into this weekly godsend of fiction wouldn't mind clicking on a few stars (or galaxies?). Of course, you would have to include a "meh" button in the middle, right?
Cheers!
