I agree with RogerS.
I can imagine it being very tiresome being a Mod.
Constantly having to step into the middle of arguments and remove abusive posts.
But if they happen to delete one side and not the other, they get accused of being biased.
It can't be easy keeping the peace.
On the other hand, I'm sure there are Mods out there who relish playing god.
It's not a position I would want.
And yes, an interesting article and a position/role we often forget about/take for granted.
