List of ideas:

* I'd agree that first and foremost, I'd change the line width. I've always found the blog a bit difficult to read on the site because of the number of words per line. The site seems to be responsive - maybe just change the width of the articles?

* It might be worth having the landing page have something other than "featured articles" right at the top. Since the content of your site is so diverse, it might help to have some pointers as to how to navigate the site up front.

* On the navigation sidebar, maybe have a "New Here?" or a "Getting Started" link.

Just some ideas. I've been reading your blog for many years, btw. It even inspired me to start my own!
