This is what I think part of the problem is. First, I have not really seen any above average quality in the posting of average NPO members when they do come on the board in comparison to regular members and even during my time in NPO I did not see a higher quality than on their boards.
Furthermore, the posting members do see will be with a strong pro NPO bias. And if this is where they get the majority of their information from, then they would end up with a very biased and misinformed viewpoint.
I have seen this happen allot in low level NPO members postings, they seem very misinformed/uninformed on events.
