It's okay that you won't ever return to them. Because one day you'll want to retrieve a specific one and then you're better off with an excess of bookmarks among which what you were looking for, than having an organised list but without what you're searching.
If you are spending toi much time chasing new links on reddit, what works for me is to limit my sources (hn and reddit only for me) and sometimes to have an offline week, proving myself that I can live without being on the top of everything.
