I have bookmarked and highlighted nearly everything I've read, by topic for the past 10 years. I agree bookmarking could be files, but the reason for keeping the bookmarks is important to consider and important not to lose. The piece that makes bookmarks hyper valuable, is remembering why or what was important about them. Annotation-centric bookmarking for me is really valuable. That usually means highlighting. There's some nice options listed in the comments, I use diigo.com for a while as a paying customer and it's quite capable. Every so often I want to see what's out there, appreciate the links In my mind I don't bookmark a page, as much as a sentence on it. First step is am I just keeping it, or reading it. If I read it, I don't want to lose that time to have to spend it again in the future. If I read, I always highlight as I go anything. It kind of makes a journal, and also helps you reinforce if what you're reading is applicable to something you're currently needing to do. The unfair advantage? When I come back to look for a link, I'm often actually looking for a sentence, phrase, or something I highlighted. I might occasionally put notes on the highlights. You can end up with dozens or hundreds of snippets explaining in and around a concept. Annotating web pages, creates a feed of those by tag, which can then be fed to other things like sharing topics with people easily. There are other tools too like Readwise that help a lot to extract the insights.
