I'm currently running a little experiment on my Internet business Coaching
blog at Article Marketing Automation VS Unique Article Wizard and Linkvana
So far, I've used 3 services (below), and I plan to use Senuke and Linkvana.
Actually, I am not subscribed to all these services, but a fellow warrior is submitting the articles for me on all those services.
1. Article Marketing Automation
I like it so far, although I didn't see the results...
