There are many old questions showing on the start page of superuser.com. If I open one of them, I see old dates both in answers, comments, and the editing time of the question.

How/why are these get to the top?

What can cause a question to be bumped?

What can cause a question to be "bumped" to the first page in the Active tab of a Stack Exchange site? (Changing the "Last Active" date.)


The following activities will cause a question to be bumped:

  • Addition of an answer
  • Editing the question or any of its answers (even if the answer is deleted) * † ‡
    • A suggested edit gets approved
  • Editing duplicates list of the question
  • Starting a new bounty (not awarding of an existing bounty, see below)
  • Successful reopening (if the question was closed previously)
  • The Community user will bump non-negatively scored, open questions every hour that have at least one answer scoring 0 and none scoring more than that.
    • Questions are picked randomly from the top-viewed questions with new activity more than 30 days ago.
    • The maximum number of unanswered questions bumped per hour depends on the site: 4 per hour on Stack Overflow, 2 per hour on Super User and Server Fault, and 1 per hour on Meta Stack Exchange and all other sites.

  • Thanks. The word "bumped" was unknown to me.
