There are 'liked' Youtube videos, subscribed channels, play lists etc. Twitter has bookmarked tweets apart from liked tweets. Hacker news has favourite comments and posts. These are just few examples of service offered bookmarks. Then we have our own bookmarked URLs of all kind of things.

Is there a solution to all these collections on various places where one can actually back to and find old interesting things again?

I made a browser extension which saves URLs and title as plain text to a local file or a service. But that does not make me go back and check those links, in-fact its the other way around because they are many. I have been thinking that it should be easier now (AI and all) but I don't know what the solution will be like.
