(Not the OP, but I have experience in this area too.)

You're on the right track. As a finishing touch, you should add role="main" to whichever element contains the main page content (in this case, the article or the most recent articles). That way, screen reader users can easily skip past all the navigation links and other auxiliary elements that are common to every page.

Sorry for being late to this thread.

You can also use some accessibility evaluation tools. I would suggest that you go here, and check the box that says "WCAG 2.0" to get some tools that check accessibility in general:

http://www.w3.org/WAI/ER/tools/

If you fix stuff that these evaluation software show you, I think your blog will be among the very well thought-out websites in terms of accessibility. WAI-ARIA is for times that your application does a lot with Javascript, such as updating a region of text, or when you start using non-semantic elements for stuff they are not meant for (for example using the i tag for an icon, or the span tag as a link, etc).
