I like the logo and the top menu. Personally, I think that it looks a little crowded with all the text. It's a little overwhelming to look at at first. I recommend that you put the nav menu on the left with a section that allows the user to search for articles. That way, there is a specific section to see those topics so they aren't all listed along the lefthand side. Also, there should be a bit more spacing between the articles on the front page. You also have 4 links to submit articles which seems excessive. Otherwise, I like the color scheme, the font, and the general content of the site.
