#Threads is probably the closest one in terms of relevant people to follow, but it has a poorly executed main page, "for you" content is preferred over people you are actually following. The UI is bases on tabs, you tap on one menu/feature etc. in order to switch to the tab you are actually interested in (followers/following, for you/following timeline and so on).
Basically you will find a lot of the people you followed on twitter but the user experience is not polished enough.
