Ask HN: “Who is hiring” less in Berlin

The "who is hiring" post for March 2018 contains the word "berlin" 7 times, and has 1187 comments.

But on 4, the post had only 997 comments and contained "berlin" 43 times. So while the comments went up, "berlin" was suddenly mentioned less. I noticed that, because I thought the current thread as too few jobs in berlin, and wanted to compare.

What could be the reason? Are people in Germany more likely to delete the comment, after finding someone for the job?
