It might bring more traffic to the other sites. For example I have almost 300 articles that I have saved to my computer. As soon as the site closes down, I will be free to publish them elsewhere. Since I already belong to hub pages I will be posting a majority here. I might have to rewrite some so they will pass the quality assessment here. I really can't think of other sites to publish to because I am afraid that the other sites will go in the same direction as Yahoo Contributor Network.
