What it doesn’t offer is an integration with the browser to make it seamless to work with those bookmarks. There are various extensions for Firefox which will save to Pinboard (one of them is mine!) but to work with them - you have the option of going to the website or using the mobile site in a sidebar (I do this, with some custom css to make it more readable for me).
There’s a nice MacOS application (sorry can’t remember the name right now) which gives you a better interface, but... they’re bookmarks. I would like them to be integrated with rather browser bookmarks. And to be usable when the site is down or I’m offline. And to appear when I search... lots of possibilities there.
