I am also not a designer so my review is from a users' perspective but I am Dutch, maybe that helps
The site looks sober but clean. Perhaps a nice image in the header that is also attractive for the visually impaired would be nice and makes the site more living.
The menu looks good and practical and the articles are well written, can't really comment on that. How do some of your visitors see a page, can they read the regular font type or do they use tools?
Have you considered adding some audio so that target group can listen to the articles, would it help your visitors?
