Meh… A good question is worth re-asking from time to time. Example:

What are some positive things happening in the world right now?

Also, some questions have answers that don’t make sense anymore or have completely new answers/perspectives due to the changing world so they’re worth re-asking. Example:

What are some dark secrets about social media companies?

Then there’s questions that just always solicit hilarity so why shouldn’t we re-ask them?

What was your worst job interview?

AskLemmy could probably have that question once a quarter and it’d be worth our upvotes 😁
