I wonder whether a user may have more than one "Hot Network Question” (HNQ) concurrently on one given SE site (i.e., >1 questions posted by the same user are HNQ at the same time in the same SE site).

    Given we don't care about users but about content I would say yes. – rene Jun 6 at 19:28

Yes. The algorithm is ignorant of question authors. According to my script, on March 31st this year at 1:06am UTC, these two Travel.SE questions posted by the same author (guess who) were present in the Hot Network Questions list:

    Wow, what a coincidence! – 41686d6564 Jun 6 at 20:20


If we study the answer from David Fullerton on What are the criteria for questions to be selected for Hot Network Questions? we find the following exclusion rules for hot questions:

  • Questions with no answers
  • Closed questions
  • Questions less than eight hours or more than 30 days old
  • Questions that were already selected to appear on the list more than 72 hours ago
  • Questions whose titles match a list of blocked keywords
  • Questions whose titles contain MathJax markup
  • Questions that a local moderator has manually removed from the list
  • Questions on per-site metas, Meta Stack Exchange, Stack Apps, and non-English sites

None of those rules mention users. We don't care about those.
