Is SEO Really What We all Need?

As you can tell I've really cranked up the posting frequency on this site. I'd love to increase the readership, and even make some money with the site. So what do I work on, SEO or content? Of course content is important, even with the best SEO crappy content means no one will stick around to actually read it.

Notice I don't have any sharing buttons on my site. First I think they clutter up stuff, and second on 99% of sites they just sit there blank. So they question is how to get readers to share the content for you?

So when I read that SEO is not the most important thing I really listen. Basically the article is a bunch of tips on writing content that users will share.
