The there are those of us that

read every scientific post and may ask an occasional question but rarely venture an opinion because we realize we

aren't qualified. Question should always be voiced, even (especially) from us laymen. It helps us better understand

the issues and concepts. Random babble is another thing and I can understand why that would upset any serious

poster.

There are all kinds of people on any public forum. But I think the majority feel they benefit from the

scientific posts, even if we don't feel we know enough to have an opinion.
