How is the Hot/Active question algorithm implemented?
Is it based on the number of:
- Views
- Answers
- Votes
- Comments
- Something else
How did StackOverflow implement a reliable algorithm for this?
Questions start out at the top of the 'Active' tab when they are first posted. A question will be "bumped" back to the top of the 'Active' tab whenever it receives a new answer, a tag is added or removed, or one of the questions/answers is edited.
The algorithm to determine 'Hot' questions is discussed here: How are “Hot” Questions Selected?
