hi chaznsc, thanks very much for sharing this article.
in the future though, we'd appreciate it if you could post a link to the article and cite just a few paragraphs to give an idea of the topic (i've taken the liberty of modifying your post to show what i mean) ; quoting the entire article can get us in trouble for copyright reasons.
actually, there is already a discussion about this article going on, so i'm going to close this thread to prevent a fragmentation of the conversation.
please continue the discussion in this thread.
