It may be good to consider what posts in Watercooler should not be about.
I like the idea of posts about politics, wars, terrorist attacks,etc not being desired here - and therefore being openly discouraged. I know it may sound unpleasant to many but even posts about the politics of global climate change. 
I am mostly concerned about how the inevitable ugly debates about such things usually may end up at being associated with SuttaCentral.
I am not sure if you have already noticed but if you use Google and search for something and SuttaCentral you may see results that point to D&D’s threads and posts.
I recommend we should keep the discussions, debates and fights of D&D separate from the blessed and liberating words preserved at SuttaCentral.
