> The thing is - I just saved bookmarks, I never really utilised them ever, to find something, to go back to.

Everyone's workflow is different, but I personally do this often. I bookmark something interesting or valuable precisely because I might want to come back to it at some point. Sometimes I do, sometimes I don't, and that's fine. But when I'm looking for good software that does X, a good place to stay in an interesting location, or a good product in a specific category, my bookmarks are the first place I check. It sure beats relying on web search results and having to navigate around ads, spam, scams, astroturfed forum discussions, morally bankrupt SEO-hacked listicle sites, social media garbage, and the modern web dumpster fire.
