Not sure what’s happening with the ranking algorithm, but it seems like the default main page is still displaying the same set of popular posts from a few days ago.
But if you switch to sorting by “Top Day,” it’ll show fresh popular posts from the past day.
For me “Hot” suddenly started showing fresh posts again after 3 days of stagnation. Nevertheless sorting by “top day” is a genius idea that I’m definitely going to use, thx for the tip!
