A particular old question was bumped to the homepage by Community. Was this done automatically by the software? Was it a person? Why was it bumped? It makes no sense to me.

I read a Meta outline of reasons for bumping, and none of them fit.

I thought that maybe the bump had resulted from an edit, but the question doesn't seem to have been edited.

    The SE Academia Meta answer I linked to wasn't quite as complete as the answer it linked to (which I hadn't noticed until now). Sometimes SE feels like Calvinball. I wish there were ONE help page containing all the basic facts. As things stand one has to hunt around for questions and answers. Jan 28, 2017 at 0:33

Visible on the question right now:

bumped to the homepage by Community 13 hours ago

The system automatically "bumps" questions that have answers where some are sitting at a score of 0 and none are accepted or score more than 0. This gives folks a chance to review the answers and vote on them or post better ones.

In this case, it worked - over the past 13 hours, one of the answers has been upvoted.

  • Helpful, but zaq's comment was even more helpful. (I don't see why the criteria couldn't be put in parentheses in the bump message.) Jan 28, 2017 at 0:29
  • Probably could be; debatable how much that matters to most folks. Also, there were concerns about pushing too hard for folks to vote - see the discussion I linked.

  • Well, people would not be required to read the fine print.... Jan 28, 2017 at 0:40

As pointed out by @zaq in a comment to an answer that has since been deleted, this answer explains that to be automatically bumped, a question should

  • be open (not locked or closed)

  • score no less than zero

  • have been inactive for 30 days

  • have no accepted answer, no answer scoring more than zero, and at least one non-deleted answer with a score of 0

Automatic bumping cannot occur more frequently than one per hour.
