Snipsly is a great site for writing articles and gaining some of the revenue share from them. All you have to do is sign up, and if you have a Google Adsense account you can enter your information to share in 80% of the advertising revenue from the posts that you write. This is better than most other sites out there and of course leads to larger revenues for the writer.
I have posted on a lot of sites, and I find that sending traffic around between all of these sites works the best for monetizing my content. Not only that, but I can choose what text anchors to my link, which is good for SEO on inbound links.
