Since yesterday I am using Ghost instead of tumblr.
echo "Hello World";
It served me well, but self-hosted has a sweeter flavor :)
I modified the default ghost theme for having different icons (e.g. diaspora icons) and adding diaspora share functionality to the post section.
You'll find the theme code here: zabica.git
For sharing posts to diaspora I am using: sharetodiaspora.github.io
