Not really a fan of the theme, too dark for my liking. Some other people my love it though.
Some pointers from me:
- Make the external links like the Twitter one to _blank so people do not leave your site.
- Get a favicon.
- Keep an RSS box at the top right corner.
- I just cannot read the text in the sidebar (bottom). Tooo dark.
- What is the form for? Mention that.
Hope this helps.
Cheers, and good luck!
