When we did them once a month they got only a few comments, but I'd say that's no problem and they're still helpful. We added that link to them in the sidebar, so that's a reason to keep them up. We should change the intro text to explicitly welcome people new to EA with any sorts of questions or observations.
To the people voting 'disagree', what OP said above is clearly true. Perhaps people are taking it to imply that the utilitarian course of action here is correct, but I see no such implication.
I think a better forum norm would be for someone to comment spelling out the perceived implication and why they disagree with it, and have other people upvote that.
