It's nice and clean, but I can't see myself growing attached to this.

The side bar needs a lot more contrast in my opinion. It's a bit hard to see, and I don't like the pattern you have at the top of each section/category - just looks out of place since the rest of the layout has a clean feel.

The structure of the blog itself isn't that bad - but there isn't a distinct enough transition from each section.

However, the style and the execution is very well done. Crisp and clean, but lacks a solid focal point and appeal.
