If I had to list 10 posters on this board who are most consistent it would be the following. This could mean any or all combinations of being fair, civil, honest, accurate, respectful, bringing interesting topics or thoughts to the table, or normally having facts to back up a debate.

I'm sure there are also many more who could fit into the (top 10 billing) but probably just don't post enough for me to remember as much so to those I apologize. Others have similar traites but tend to jump all over posts at times before thinking things through. Or, simply have a hard time seeing both sides of a discussion more than others.
