Oddbean new post about login | logout I used to think chronological only was the only option that wasn't "bad" but more and more I'm realizing I'd really enjoy not missing posts from people who post infrequently, or something big happened but I missed it because of later posts pushing it beyond scrolling.
Totally agree, and with hundreds of millions of posts, it's not going to know what particular one you wanted to revisit. However I would like to plug in an algorithm of my choosing and I would have my client remember every post it has ever showed me, like a "seen posts" list.
