If you prefer content to creating your own personal blog appearances, Medium (http://medium.com/) is the best option. I did use Tumblr and Wordpress for quite some time over the years on multiple non-developer blogs.
The first few years in my career when I'd code for a few hours non-stop then crash on the beanbag at my desk, I dreamt a lot of bug fixes, very few of which stuck in my mind after I woke up. It's basically the last thought I had before I went to sleep which affected my dreams all my life. If that last thought is code, then so is the content of the dream.
