Blog Layout

If anyone has suggestions for the blog's layout and CSS, I welcome ideas. I do, for the most part, wish to keep the colors simple and the interface minimal. It is all about the content in the posts, after all. I confess I am a bit rusty with xhtml/CSS, but can easily switch things around as needed. If the layout is difficult for you to read, navigate, or understand, please contact me in some way and let me know!
