Several users in the past contacted me and complained that it is confusing that I offer English content on a German top-level domain. While I think that is a bit silly, I also grew found over time with the though of using vogella.com.
So here it is, I migrated to vogella.com, please update your bookmarks. I setup re-directs so for most things you should be fine. But if you syndicated my blog you may want to update your links.
In case you find issues, please let me know.
