A guy in UK who goes by Oz, a very reputable IM, put out a WP plugin that allows you to extract content from articles sites based your keyword, then wrap the intact article - complete with the attribution link back to the author - with a leading paragraph and ending paragraph (or more, if you want). He claims this allows you to rank for kw quickly, provided you do your diligence about competition vs search volume, and even though you're recycling content, you'll never be banned or penalized for duplicate content. Have you tried it and what has your experience been? Did you see rankings rise? How quickly? Did you see any rankings drop after the Farmer release?
