I made an app that shows me N of my previous bookmarks per day at random, loosely following spaced repetition. Seeing the same articles/conversations/tutorials multiple times helps me to recall them when needed, and I sometimes have serendipitous ideas.
I've been doing this for years and it's amazing how much of the internet is broken. Maybe 20% of my bookmarks don't load and require the wayback machine. hacker news comment pages always work though :)
