So finally it is done: I moved my blog from Drupal to Octopress. I did not migrate the old posts form the Drupal blog, this would not have been worth the effort. Due to the good documentation it was quit easy to get started playing around with Octopress. In the end I only did some minor changes to the default theme to get satisfied with the look.
So let’s see if I will use the blog more than the old one.
