The question is not so much "duplication" as "dilution" of the article. If the goal is to achieve visitors to your site, then post/show only original content on the site. If others allow you to post an infomercial of that article on theirs, ie, a link with short description, that's okay. But if you give it all away every place you go there's no reason for the visitor to come see you... they already have the content and will be off the sniff the next flower that interests them. And if they find the same thing on multiple sites (under YOUR NAME) they just might get the idea it's not worth much. Just my 2 cents, adjusted by inflation to .000002 cents.
