I currently am in the bad habit of bookmarking websites and never, ever viewing my bookmarks.

;) It's like hoarding... I hoard links and knowledge, but rarely go back to them. I think I need therapy.

The one time I ever looked at my bookmarks was when I was on a long flight bored of my laptop with no internet, then I realized I had used an extension that cached my bookmark content so I read a bunch of articles, blog posts, and HN comment threads.

Never touched them again.

I don't think you should stress yourself out by viewing everything solely from a productivity perspective. I use Linkding and have bookmarks for everything that interests me. I see it more as a personal history or memory that I can refer back to. Linkding has a very good search function for this and can also be integrated into Google or SearxNG search results via a Chrome extension.

I hit Ctrl+Shift+D on dozens of tabs multiple times a day.

Browser search does work pretty good tho for something like pulling that specific article I saw on the New Yorker last week or the new pizza restaurant I came across last month.

What's wrong with that, though, really? I like my collection of forgotten bookmarks. I also write a journal that I almost never read. So what? It's nice to have. Collecting passing notions is nice.
