I've been using Trello for a while to organise bookmarks and other snippets, but with the recent force-in to rich text instead of markdown and links displaying as "preview" by default the UX has got a lot worse. Yes, there are extensions that make it almost as good as before, and I'm using one, but still.

From the article, I gather that it turns out that filesystems are a good way to organise vaguely hierarchical information. SQLite isn't terrible though either, people should be able to write third-party tools to help manage that.
