Why not? In what way this is worse than having the same column of content centered or on the left side of the page?
I find it refreshingly different.
Hi, it's just a blog, not a paid job. Not a lot of effort went into it. I'll take a look when I have a chance (it looks fine on my MBP and several others).
I don't think it's broken. It just looks pretty cramped and weird if you've got your browser in a portrait orientation.
