A few weeks ago I started a german blog at bjoernguenzel.de. I finally wanted to use the domain to promote myself. However, I feel that blogging in english is much more interesting, especially when writing about information technology and other science subjects. Therefore I will probably write most of my new posts here, and limit the german blog to topics that are only relevant to Germany, or that already have had much traction in english, but less so in german.
Maybe a dual-language blog would have been more elegant, but to be honest I am not sure if WordPress supports it, and could not be bothered to set it up. Also, blinker.net is my primary domain, and bjoernguenzel.de was more of an afterthought.
