If the FR powers regard duplicate articles as a bad thing, I wonder why the latest FR software doesn't include (1) the admonition and tools to perform the Search on the Post page itself, or (even better, 2) when the article is submitted for posting, an automatic search which would progressively search the title and, if necessary, the first n words of the article, then compare them against the articles posted within the past n hours. Any possible dupe(s) could be presented to the poster, giving him the last say in whether his article should be posted.
Call me a geek, I guess. The shoe fits all too well sometimes.
