That’s a big challenge indeed! I enjoy pinboard quite a lot, but I stopped using it for a while. Now I manage all my bookmarks from a simple text file on emacs, I store the links there indifferently of the protocole they use, and since I use emacs for browsing it makes the thing convenient. However it doesn’t sync on my phone or other computers!
Ah that is a good solution. I could do the same opening the link with the appropriate browser. And a text file is easy to sync across devices. I'll try :)
