This is just a reminder that before one posts an article, one should check to see if the article has been previously posted in order to avoid duplication. Duplication causes several problems. Just like the old Monty Python skit about spam, if the same thing is posted over and over, it can drown out other valid posts. It needlessly consumes system resources. It fragments discussion. In general, moderators will pull duplicate postings when we are alerted to them or when we notice them. This has the benefit of eliminating the "spam" effect and it helps keep discussion from being fragmented....
