i think you're talking about trending vs popular.
The signals are working as intended. More people will know Kim K than Sweeney because Kim K is more popular and has had more time to be more popular.
why am i talking about kim k on hn lol
Everything I learned about the Kardashians has been learned against my will.
The signals aren't really working though. It's why algorithms are required, because people want relevance instead of popularity.
Having fading connections equates relevance with popularity.
