I think mods should only come into play when either there is someone who is making an all-out attack on the board and individuals with the aim of just making everyone miserable or in the case of someone who has simply gone over the edge and has so much anger and pain that it just overwhelms everyone.
What we read here the last few days was pretty damn ugly but in my thinking if people knew a big eraser was coming and that they could say whatever they wanted and be obnoxious as possible, they would have less incentive to be more controlled and civil. As it is, some people made complete asses of themselves and continue to do so but really don't seem to care. To each his own, I say but if I knew my dirty laundry was going to be on display for everyone to see, I would be more careful before sticking my foot in my mouth and engaging in all out flame wars or expelling mental vomit.
I did think Simon did the right thing by locking one or some of the threads because some people just get so caught up sometimes that they just revert to their reptilian brains and lash out at each other to no end.
Personally, my choice for action if something like this happens again is for other posters to point out how ridiculous and foolish their online friends are making themselves look, regardless of if they are "right" or "wrong" and if they can't debate things without reverting to insults, character assinations and the like, they need to buy themselves a copy of "How To Get Along With Difficult People."
