I would highly recommend taking a look at www.ghost.org

I use it for my online presence to essentially talk about the same thing that you are. It is very simple to use and made for a great, clean reading experience. I am just using the default theme provided because I like the simplicity and elegance of it. Feel free to browse to my website to get a feel for it.

P.S. It requires a dedicated capable of running node.js apps, I recommend Digital Ocean for this. You can get just what you need to start at $5 a month.

Hope this helps! :D
