Screen reading applications, including Apple's VoiceOver, improperly pronounce the word "content" in "Skip to content" as an adjective rather than a noun because of insufficient context. "Skip to main content" is pronounced correctly.
See #6 and Guideline #10 at the following site for more information:

<p>If your navigation contains many links and comes before the main content in the DOM, add a <code>Skip to content</code> link immediately after your opening <code><body></code> tag. <a href="http://a11yproject.com/posts/skip-nav-links/">(read why)</a></p>
{% highlight html %}

- <a href="#content" class="sr-only">Skip to content</a>
+ <a href="#content" class="sr-only">Skip to main content</a>
<div class="container" id="content">
