Ideally I'd like to have a minimal OS and file set on my local machine (for offline and poor connectivity scenarios), that automatically syncs with my own, encrypted cloud system, such that I can (at my own discretion) update the OS from controlled sources (e.g. git). But I don't think there is enough interest from others for such a system, and I'm occupied with enough other projects that I won't be able to set up such a system.
I think that it depends on your use-case. I use Google Photos to store my media files, Github to store application configuration & source code of my applications, Chrome to store bookmarks, passwords, Spotify to save & listen music etc. Even if I lost my computer now, I would easily setup my desktop environment again.
For me, I don't use Google Photos or Spotify, I have my own local copies and maintain my own backups.
I do use Github for some projects, but I also maintain local copies and maintain my own backups for all my projects.
If pinboard.in ever disappeared, it'd be like loosing an appendage! It might not be as bad as loosing an entire arm or leg, but its loss would be equivalent to at least a finger or two!
