@ LaurieA,

The first question I have is if you only come here for information, why do you care about posts by individuals who disagree with you/or who you disagree with?

Would absolute uncritical agreement improve the value of the information you seek? Really? Why do you think this?

Most social-networking sites suffer the death of lameness expressly because they enable such "reality-filtering." This filtering by definition degrades the value of any information offered.

Humans will never all "just get along." Do you think they should? Why would this be a good thing?

Asking people to all "play nicely" is asking them to not communicate honestly. Why would this be a good thing? Do you think dishonest communication would = better information? Why would this be true?
