I considered that point of confusion too, but I decided I'm OK with people who are unfamiliar with the term "office hours" needing to click through and read the article. I picked "consider running office hours" because hopefully the word "running" there is slightly less likely to imply "consider only working 9-5pm".
I've added a note about the better German term "Sprechstunde" to both the article and my Calendly description: https://calendly.com/swillison/datasette-office-hours
