I do, but I have them export and upload to my server daily so I can keep them in sync. I don't organize them, I just use search and find. They're all relevant links I wish to look at or read at a later date.
They are uploaded via scripts or manually to my server, which I then can view a list of all the items. I dont remember everything, but I generally remember enough to find the item again. I don't have thousands either. In the past I have created a custom bookmarker site but switched servers and never set it up again, this method is much faster for me since its integrated into my browser already, bookmark and done. I also only save relevant content, guides, tutorials, that type of stuff.
