Related question - how many bookmarks do you have and how do you use them? Because for my use I don't see a point of doing anything fancier that Ctrl-D to bookmark and keeping them in <5 folders in my browser.
I am archiving many links in my desktop browser (about 50 folders with various subfolders and each with a dozen links). The problem is that I would also like to have them available on mobile devices. Sure, most of the time you will not need them again. But with increasing regularity I am remembering that I was reading something interesting somewhere and want to have a look again, but can't find it in the web anymore. Then, you can figure out more easily where you read it when having appropriate and well-structured bookmarks.
