Interesting, your site has a similar feel to mine, and our focus is similar - content, content, and content. Readability is key!
I like your site and will bookmark it to see your progress. I want to track how you respond to things. Again, we seem to have a similar design attitude. I hope you agree and that you think that is positive.
One immediate comment - your horizontal black separation bars seem to strong. They are overpowering the other page elements. They need to be strong enough to separate and organize but not too strong to detract.
Sometimes, it is helpful to squint with your eyes at something and see what stands out. There should be balance, not mush, but balance.
There is so much about your site that I like. Oh, whenever you create a link to another site, i.e. Moleskin (great notebooks by the way), have them open in another tab so you don't lose the individual to that other site.
And another thing, I am learning that post/page titles are very very important for higher SEO. They need to be catchy to pull you in but they should pull from words and thoughts in the article. If someone were to find the article in a search, would words in the title be ones that they would think of using as keywords?
Enough, God bless
