If you're posting the exact same article in multiple locations, google will likely only show one of them in the SERPs. If you want it to possibly show up in SERPs on your site AND on ezinearticles, you will need to vary the content.
However, if you goal is to build inbound links, don't worry about it. The "penalty" is only in SERPs, not on value passed by the link.
Thanks, for the clarifying this for me. So my site would not take a hit or penalty if I had the same article on ezine and my suite. Google would still give me credit it would just choose which link to give the credit too ?
