Every time I wipe my laptop drive and reinstall from an image I always create a "Sonar" bookmarks folder in Firefox. If there is something that is particularly useful I bookmark it into that folder. Before I wipe the drive again I export and backup all the bookmarks to an external drive.
Ideally I would import the backups on to the fresh Win/FF install but I never seem to BUT I do still have all those backups saved. One day I will sit down, import all those backups and sort them all into a master file.
I have a ton of other music and computer related bookmarks as well. One day I will create a master file of everything I've collected over the years (articles, vids, tuts, useful sites, etc) and maybe release it to the forum.
I also have an ever growing master folder where I store all all my local tuts, manuals, vids and personal notes (I use notepad instead of other text editors because I want raw text for various reasons). That continually gets updated and is my main go to if I need to figure something out or have time to do an in depth study of something (in the latter case I create or update my note files on the subject).
It is still a little chaotic but I've been refining this system for the past few years and it is getting easier and easier to go back and reference it all.
PS: And I found when I make notes on vid tuts or specific manuals I keep them in the same folder as the actual material. I did try keeping it all in one big document but that got WAY too crazy WAY too fast. One main folder with subdirectories was way easier to manage/edit, navigate and backup.
