Now, having said all this, I believe you should combine article marketing with other organic traffic sources. So instead of just writing 10 articles a day and submitting all of them to your favorite article directory, I suggest putting 5 on the directory, and put the other 5 on 5 different blog sites or forums, and put links pointing to the articles you put in your favorite article directory.
So you might put one on your site, put one on a site where you guest-blog, one on a forum where you have positioned yourself as an industry or niche Asia Email List expert, one on someone else's site, and one on an industry or niche site.Then promote all the articles to your list, to your Facebook contacts, to your linked in contacts, etc. Suggest people like them, Google+ them, etc. so that you gain some real social traction for your articles.
The key here is promotion. You want to get maximum eyeballs to all the articles, and the best way to do that is to have all the articles promoting a few other instances of your articles on different sites. Get people linking to them in their Google+ accounts, Facebook walls, linked in profiles and pages, and everywhere else where people are interacting with you.
