> I have hundreds of bookmarks that I may not be using right now but end up being useful years later.

I pulled up an old bookmark file that I had backed up on CD-R and pretty much every single link was dead. So at best, it was just a memory of something that I thought was worth saving at one point and might go back to someday. So more like what you said: "history of things I've found that are interesting" but not being able to use them to get the website (unless it's in Wayback Machine perhaps).
