A potential drawback to measuring and publishing a Most Controversial Nodes list would be that of encouraging controversy for controversy's sake.

I enjoy as much as the next monk heated discussions, debate, and especially the multiplicity of viewpoints, opinions, and experiences that folks bring to the Monastery.   But I moreso enjoy Perl Monks as an oasis of civil, considerate behavior amidst the often rude and flaming desert that is the Internet.

So my guess is that the interesting info and feedback that Most Controversial Nodes would provide could easily be overshadowed by negative impact.   KnowwhatImeanVerne?
