This question already has an answer here:
In theory, hot questions are intended to be a buzz feed like list of "neat stuff from across the Stack Exchange network."
Could we get them to age a little bit faster? It gets rather boring seeing the same question for an extended period of time.
As I'm typing this, I see on the side a box with a question that I've seen before.
This question, when going to the original site:
This is really getting old. Yes, it has 1000 views/day... but I've seen it for two weeks show up on the side. Surely across 152 sites, there has to be something that has only been around for a few days that would do better to provide a continuing interest in the other sites on the network rather than continuing the display of a post that was community protected (deleted posts? new user answers?) a week ago.
Make it something fresh to look at rather than something that makes me wonder about blocking them.
(Related and apparently status-completed Don't let questions stick to the top of the hot questions list forever )
From an answer there
I agree that two weeks was extreme for that question, but as you can see, it is no longer present.
That is also a very, very rare event. Can you think of another time that has happened since we introduced the MultiCollider?
I don't think we need to rearchitect the entire se.com cross-site hotness algorithm on the basis of a few hundred year floods.
Apparently, these aren't 100 year floods. They're about monthly occurrences.
