The Internet - Has it

I do have a board and it runs basically like this one. The only stipulation I have is no flaming. I feel you can answer questions and disagree without resorting to name calling and personal assaults.
I know over the past few years I have disagreed with Jim Booth, Porter, CC, Freix, and others that are considered to be knowledgable. I have also agreed with the same bunch. How does someone say this one will be right and this one won't. The only way these boards work is to have a free flow and try to reach a concensus.
