Hmm. It's easy to declare a "squee-only zone," but "squee or constructive criticism only" would be tricker, since I have the nagging sense that a lot of the people coming around to express their personal outrage at the current or projected future direction of the show would in fact consider their opinions to be "constructive criticism." And, yeah, what musesfool said above, the thing where people comment with what they said in their own journal because they figure you aren't likely to have read it there and theirs is an opinion worth spreading -- especially if they think you're wrong and need correcting.

I'm not sure how to phrase the guidelines for that. "I'm a fan of this show. I don't need to hear comments in my personal journal about how much you hated everything about it." From a practical standpoint, flocking and filtering your DW posts and eliminating the people demonstrating an ongoing tendency to squee-harshing would probably take care of the problem but would be a certain amount of trouble to set up. You could hold off on it for another week or two and see if your request has any effect on correcting the problem. (Actually, you could hold off a few months, since we've only got one more new ep before the hiatus anyway. Let the problem mull in the back of your mind and see if it's an issue again in the second half of the season.)
