You, sir or madam, are an idiot. It's been said before, but it bears repeating, rating down a thread only serves to add a positive net to the karma ratings of those in the Asylum. Your devious little ratedown of someone from 4.02 to 3.44 will only serve to bump them up multiple times to 5.00. So, I guess if it is your intent to raise everyone's average karma, knock yourself out. Otherwise, may I suggest a bit more subtlety and just take down a score here and there as you feel the content warrants?
I suppose its possible someone is rating down threads with the intent of raising everyone's karma...
