I like simple themes, so no problem for me there. I am not fond of the double nav bar on the right. It gets a little busy.
I don't know why so many blog themes have nav bars on the right when, statistically speaking, people find left nav bars much more user friendly.
One thing I think you should work on, to keep people reading all the way through your posts, is to make shorter paragraphs. Break them up a bit and add a few sub headings. Long paragraphs scare people away.
Other than that, very nice blog. Good job. :biggrin:
