A defense of bookmarks
Bookmarks are unfashionable. They feel like 2004. But when I want to find something I read three years ago, the bookmark is there and the algorithmic feed is not.
I keep mine in a single flat folder. No nesting, no tags. Just a long list, sorted by date added. When the list gets too long, I delete the bottom half. Nothing of value is ever lost, because anything truly valuable, I bookmarked again later.
