Just had a quick look:
- Top menu items don't stand out enough
- Have never understood why a website would have the current date and time printed on them - seems unecessary to me
- Could combine your JS files into a single file to reduce HTTP request - do the same for the CSS files
- Top search needs a button - not everyone would know you can press enter. alternatively, make it search automatically when a term has been typed into it
- Never been a huge fan of square full page backgrounds like that - makes the site look odd to me. Fading out the edges of the background looks better imo.
