[dificilis]

I tried Pocket, but it wouldn't let me edit titles, which was a bit of a deal-killer. So then I tried Raindrop (free plan), and I have been using that ever since.

I use "collections" to describe abstract properties of a bookmark, like "work" for work-related, "reference" for 'I have read it but I might want to refer to it later'. Then I use tags for identifying topic - but a lot of the time there's enough info in the title, and tags don't really add much for the effort involved.
