What does this mean ? Who are these ezine publishers and how does it help me ? Will this improve my views and sales ? Or is this just normal ?
They are people who've taken your article and published on their own website. EZA has a button you can click to preformat the article or something, and that counts as a "publish". There are way more people who just copy and paste from the actual article itself that don't get counted.
Yes because if they use your article they have to keep the resource box intact which means more links to your site and hopefully more clickthroughs.
