Okay, I will admit I didn't read all of your post but the title resonates with something I struggle with. I have thousands of bookmarks and things I want to follow up on, but retrieving these and digging into them is effort, so they just sit there... things I was interested in, but don't have time to properly investigate.

If someone could make an AI tool that takes all of my bookmarks and surfaces one or two insights from them to me per day, I.E., "hey you bookmarked the wikipedia page for this movie director, did you know one of his movies was just added to netflix?" or "Hey, you bookmarked the Kotlin website, want to try making a Kotlin project? Here are some app recommendations based on your other bookmarks..."
