I am not a coder (except for some practical PHP and trying to learn Ruby in my spare time), so I have absolutely no idea what anything means on that site

. With that said, I have a lot of comments about the site:
- I don't really like the homepage layout. I'm on my laptop and I pretty much only see the menu, the blue "splash" box, and this red/yellow/blue/green graphic that I don't really understand the purpose of? I say I don't like the layout because the welcome message and links to recent posts is basically stuffed underneath the above, as if they are secondary in importance, when they should be 1st, IMO.
- I feel that you should completely redesign your responsive menu so that it takes up less space. As it is, each menu item is expanded, has a lot of padding, and takes up an entire screen. Common methods I see are either a dropdown menu or a click-to-expand menu, with those dashed lines as the icon representing "click me to see menu." It's also hard to distinguish where the menu ends and where the body begins. I believe this can be remedied by making the menu background dark, so as people scroll, they will see a different background color, which would help indicate the start of a new section.
- Images should be max-width:100%. See about page, there is a picture that is wider than screen.
