My bookmarks have not changed in a long time. I use the same bookmarks. I never really use the service, because I never really use bookmarks all that much, I’ll just Google something. I found the bookmarks get on wielding and I start losing track of them and I start having lists of bookmarks that are 9 years old.
Rather than bookmarks I use Pocket. It’s been very helpful especially for articles and technical websites that I want to be able to reference later.
