I use bookmark tags a lot, and rely on them to quickly find things in future.

I bookmark all sorts of things. Projects or articles that I think I'll likely need in future, issues which I report and might need to reference in future, etc.

I'm sure over 50% of my bookmark were written and never read, but I definitely query all sorts of old bookmarks nearly every day.

Thank you! I have similar issues with bookmark managers overall. When they are too far from where I use them, it turns into a list of links I never read

In Arc, I'd organize links in dedicated workspaces for each project (personal or work). So whenever I work on a specific project, I'd open that workspace and have all the necessary links right there. For example, I tend to check Product Hunt often, and I have a dedicated workspace where I'd store products organized by my personal use cases. So next time I'm looking for a tool for something, I'd just open that workspace and search

I use Obsidian (other note-taking apps and editor modes are available) and generally write at least a sentence about each bookmark. Subject areas get their own notes/bookmarks and I use the available linking and tagging options to try to make the resource more useful and easier to refer to in the future.
