When I review a site like Author Earnings dot com (no affiliation, other than being a huge fan of such an amazing amount of free and open data) it shows pretty clearly that, "An Indie author can make it." In fact, the bulk of the data shows Indies have as good a chance, or better, at cracking the best seller list on the site.
For free, on both sides of the interest pool for authors and readers, there is a ton of value and a growing amount of it. Then if you start looking at other models like Issuu (recently on the app store, after long absence) and Wattpad, it really makes you scratch your head at the tone of the article.
Without the preface, "For newbies to the publishing category," it reads like a poorly articulated puff piece. Sorry.
