i think this is an important topic. even in the best communities, people get stuck on ideas and don't know how to listen. in this, i'm defining listening as being open to the other persons ideas, acknowledging that other persons worth even if you disagree, and separating the idea from the person. some people, if they dont like a person, reject their ideas out of hand because of the inherent hostility they feel. or, if they are tied to their ideas, they reject any change out of hand as if the idea was a tenant in a religion. being flexible and open to change is healthy.
