After a bit more than 13 years I now removed Disqus from the blog.
Over these years, it only contributed 36 comments.
Most of them around a single post that made it onto the frontpage of Hacker News and Reddit.

I'll extract these comments from the export file of Disqus.
Then backfill them as static entries to the corresponding posts so they are preserved.

In the future I might add another way to comment/contribute directly on the blog.
For now, please use the communication channels listed on the About page.
