You have an idea for a good article. You take the time to craft it and write it well. The next step is to either put it on your own website or release it into the blogosphere. If you decide upon the latter here is a resource for you.
This is my list of the top 5 places to submit articles. They are all quality sites with good page rank and they have do follow links. There are a lot more sites but these are the cream of the crop. I suggest you focus here.
Helium no longer has the do-follow tag so you will no longer pickup a back-link but there are other benefits when you write for them.
