Built to remember. So you don't have to.
Folders don't scale. A folder system works at 30 links and breaks at 300. By 600 you're nesting folders inside folders and renaming "Misc / Misc 2 / TempThings". The problem isn't you — it's that hierarchies don't match how your brain wants to retrieve things.
Search is missing or broken. Chrome's bookmark search finds matches by title — and most pages have garbage titles like "Untitled" or "Home - Welcome | Site Name". You can't search by what the page is about, because bookmarks don't store that.
Sync is chaos. You bookmark something on your phone. It maybe shows up on your laptop 20 minutes later. iOS Reading List, Chrome Bookmarks, and Edge Favorites are three separate kingdoms that don't talk to each other. The link you saved last week might be in any of them.
