I pay for Pinboard. I have 5K bookmarks and daily add about 1-10 new ones. I will never read most of them. But when push comes to shove, I can easily find that BioTech article that generated a lot of discussion on HN because I tagged it as "hn" and "biotech". And if that article disappears from the web, Pinboard should still have a cached version. So now I can bookmark an article close tab #231 and fall asleep peacefully.
