i agree with pinkster here... I notice that people tend to give a negative Reputation with no explain.. or giving a postive reputation without explain.. this sounds silly to me..
giving a negative reputation without explaination of why its bad post is a rude form of giving people bad reps..
also why would people simply disagree with you on something and give you a bad reputation? a bad reputation is just for Bad post.. bad influence, or so... not just cuz u disagree..
