Since late 2017 I’ve mostly moved from Twitter to Mastodon where I have multiple accounts:

  • This is my primary account where I write about pretty much everything I care about.
  • has tons of authors and sci-fi fans so this is where I mostly write about the books that I’m reading and if there is something sci-fi-related.
  • is where lots of people from the German hacker and security scene are. I’m mostly here for hacker-space and related topics.
