Keep a reading list that works
A pile of saved links only becomes a reading list once you can sort it. The links you keep should be the ones you'll actually return to, and structure is what makes that possible.
What Margin does
Margin, our fictional reading-list app, stores three things for each link: a title, URL, and category. You can filter by category and bookmark items you want to come back to. Everything stays in your browser; there's no account and no cloud sync, which keeps things simple.
A weekly review
Go through the list once a week. Remove the links you no longer want to read, and keep the ones tied to a project you're working on. A small, focused list beats a big collection you never open.
