I disagree. There's a new idiot introducing himself every week.
Well you kinda proved my point. You said "a new idiot" instead of "new idiots". A board on a site this big should have more new people coming in than one or two a week.
Look at this thread as an example. As I type this there are 19 replies from members who joined in
2012 (you again)
2011 (JDM again)
2012 (Harry Ballzack)
In short, like I said, the OT is simply now growing any longer. Not saying that's a positive or a negative. Each person will have their own opinion whether or not new traffic to a message board is a good or bad thing.
