I've noticed recently that a lot of old questions are showing up in the main feed on the site (what you get when you go to rpg.stackexchange.com under 'Top Questions' without applying any filters). This is, presumably, because people are editing old answers or are answering old questions.
Is the Stack algorithm bumping old questions up and making them more visible to users or what? I keep seeing questions there that I think are new that turn out to be quite old (on the order of years in most cases).
When I click 'Questions' on the main site and sort by newest, I get what I would normally expect to see on the main feed (new questions, sorted by their "newness").
To be clear, my question is specifically regarding the behavior of the main site feed -- the display of questions on the default rpg.stackexchange.com 'Top Questions' listing, which seems to have a lot of activity from very old questions lately. It's not a concern or a problem, just wondering if the behavior of the main feed has been modified in some way, because it seems, well, different.
