Waited a bit to see if anyone would chime in. For me, "offers" of content like this are examined very closely. These type of postings/articles are for the poster's benefit, not the site owners, ad in most cases are just a form of link dev to credit their sites. However, sometimes one can get a nice article/post and not give up all that much. Take each on a case by case basis, but do know it is usually for their good, not yours.
