well respected blogs such as Ezines Articles? I don't think they are well respected since February 2011.
I'd suggest you to focus on your site - Build your own content first. Only after you're satisfied with the results, plus constructed your content wisely (so that users will find it useful and link to it from their own blogs or share it in social media), think about partnering with key players in your vertical. Partnering in a way that you link to them (and vise versa) from the content so that users get more info on the subject matter. Artificial link-building such as links from article directories is the proof way for Google to put your site on trash from its day one.
Addressing the question I would like to mention that no one can deny the fact that almost everyone with a website is there for his/her business but then the poor fact is that many wants to just make money without giving the reasons to their prospected leads.
It's web, competition though is tough here but you can get the edge with the help of content marketing, social medias and as a resourceful and knowledgeable index.
Don't look for authority on web, Work on building your own authority.
