Recommendation algorithms could be good and helpful in some cases. I use one I made to help me find posts from people who don't post often and thus their posts get buried here.
A simple:
show me one (1) post from each person I follow from the last month is very powerful for finding out what people who are less active are posting. You know those people who only post like once a week... but then it's always some amazing photo they took or an incredible insight on some event.
