If it is ok to second a POTM then it should also be possible to post a disagreement. The discussion should NOT discuss the merits of the content of the post but the quality of the post.
I agree. I actually think there should be NO discussion (seconding or disagreement); the whole point is to avoid clutter. POTM is a nice, clean index. If we open things up to disagreement, we open things up to a lot more discussion, and the POTM forum loses a lot of it's value.
What would be absolutely AWESOME, IMHO, is if each POTM nomination automatically included a survey, and we could vote on the quality of any POTM nomination. That would help point out where there's disagreement about POTM nominations, while completely eliminating the need for any discussion.
I know there's no way Percy can do this. The Queen set up a poll a while ago; I'm wondering how hard it would be to do it manually for each POTM nomination.
If anybody wants to discuss the idea, I encourage you to take it to the "Feature Requests" thread in the "Suggestions and Questions" forum.
