I have used several forums over the years and have noticed a phenomenon that I cannot explain. It's not universal, but it seems quite common. Why is it that so many times the first poster after the original poster's question doesn't know the answer yet still posts? Many times the second post is verbose and wandering, yet the poster still doesn't know the answer. Why do they post if they don't know the answer? (Can't wait to see the second post here. )
