If you go back to the beginning, I said they shouldn't impliment it (actually I think I got a lot of rep for saying that

).
Later I came to understand, for me at least, that sometimes when someone pushed my /rage button I could disarm that flamewar and not play the game by just -repping instead of responding and joining a flamewar. It was a pressure relief valve of sorts, and that let me see some value in it for promoting a calmer community.
The abilty to neg rep for HORRIBLY bad advice so newbies didn't take advice from people giving out harmful advice also seemed to be good for the community. (And I'm not talking "I disagree with you" type stuff, I'm talking about over the top wrong to the point where it would harm players who followed it type advice)
Given the recent changes to what rep is or isn't... I can't really see any value left in it, so I guess I'm coming back around to the position that it doesn't promote community or seem to serve any positive purpose, and thus maybe it should be turned off.
And my comments about the mods above should be taken with a grain of salt... the smiley was there for a reason. Of course the mods are going to moderate with bias - they are there to achieve an objective for Turbine, not to create a free and open public forum. That's not bad, its what they need to do. (Even if I don't always like where they land, that's another issue entirely

)
