hackwrench writes: Most reviews of so-called bookmark managers focus on the fact that they can share bookmarks across browsers and devices and whether or not they can make your bookmarks public or not. Sometimes they mention that you can annotate bookmarks. Little is said about real management features like making certain bookmarks exclusive to one or a set of browsers or devices, checking for dead links and maybe even looking them up on archive.org. I'm sure this isn't an exhaustive list of features that would be good to have. What bookmarks managers do you use and why, and what features would you like to see in a bookmark manager?
