Hi, I have a question - let's say you write a good, quality article (blogpost) on your site. You, of course, make another version of it and place it on ezinearticles, perhaps goarticles, squidoo etc. The question is, is it worth it to place it on tens of different article sites? I mean, are the backlinks valuable? Or should you just post a couplecopies of the changed article on the main article sites and don't over do it?
Thanks alot for the answer, hopefully I've expressed the question clearly enough.
